Acne

The Comparison

A A 25-year-old man of Hispanic ethnicity with pink papules, pustules, and large keloidal tumors on the occipital scalp characteristic of acne keloidalis nuchae (AKN). There is hair loss and some tufting of remaining hairs.

B A 17-year-old adolescent boy of African descent with small papules on the occipital scalp and some hair loss from AKN.

C A 19-year-old man of African descent with extensive papules and keloidal tumors on the occipital scalp as well as scarring hair loss and tufting of hairs from AKN.

Acne keloidalis nuchae (AKN) is a chronic inflammatory condition commonly affecting the occipital scalp and posterior neck. It causes discrete or extensive fibrosing papules that may coalesce to form pronounced ­tumorlike masses^1,2 with scarring alopecia (Figure, A–C).³ Pustules, hair tufts, secondary bacterial infections, abscesses, and sinus tracts also may occur.¹ The pathogenesis of AKN has been characterized as varying stages of follicular inflammation at the infundibular and isthmus levels followed by fibrotic occlusion of the ­follicular lumen.⁴ Pruritus, pain, bleeding, oozing, and a feeling of scalp tightness may occur.^1,5

Umar et al⁶ performed a retrospective review of 108 men with AKN—58% of African descent, 37% Hispanic, 3% Asian, and 2% Middle Eastern—and proposed a 3-tier classification system for AKN. Tier 1 focused on the distribution and sagittal spread of AKN lesions between the clinical demarcation lines of the occipital notch and posterior hairline. Tier 2 focused on the type of lesions present—discrete papules or nodules, coalescing/abutting lesions, plaques (raised, atrophic, or indurated), or dome-shaped tumoral masses. Tier 3 focused on the presence or absence of co-existing dissecting cellulitis or folliculitis decalvans.⁶

Epidemiology

Acne keloidalis nuchae primarily manifests in adolescent and adult men of African or Afro-Caribbean descent.⁷ Among African American men, the prevalence of AKN ranges from 0.5% to 13.6%.⁸ Similar ranges have been reported among Nigerian, South African, and West African men.¹ Acne keloidalis nuchae also affects Asian and Hispanic men but rarely is seen in non-Hispanic White men or in women of any ethnicity.^9,10 The male to female ratio is 20:1.^1,11 Hair texture, hairstyling practices such as closely shaved or faded haircuts, and genetics likely contribute to development of AKN. Sports and occupations that require the use of headgear or a tight collar may increase the risk for AKN.¹²

Key clinical features in people with darker skin tones

• The lesions of AKN range in color from pink to dark brown or black. Postinflammatory hyperpigmentation or hyperchromia may be present around AKN lesions.
• Chronicity of AKN may lead to extended use of high-potency topical or intralesional corticosteroids, which causes transient or long-lasting hypopigmentation, especially in those with darker skin tones.

Worth noting

• Acne keloidalis nuchae can be disfiguring, which negatively impacts quality of life and self-esteem.¹²
• Some occupations (eg, military, police) have hair policies that may not be favorable to those with or at risk for AKN.
• Patients with AKN are 2 to 3 times more likely to present with metabolic syndrome, hypertension, type 2 diabetes mellitus, or obesity.¹³

Treatment

There are no treatments approved by the US Food and Drug Administration specifically for AKN. Treatment approaches are based on the pathophysiology, secondary impacts on the skin, and disease severity. Growing out the hair may prevent worsening and/or decrease the risk for new lesions.⁶

• Options include but are not limited to topical and systemic therapies (eg, topical corticosteroids, oral or topical antibiotics, isotretinoin, topical retinoids, imiquimod, pimecrolimus), light devices (eg, phototherapy, laser), ablative therapies (eg, laser, cryotherapy, radiotherapy), and surgery (eg, excision, follicular unit excision), often in combination.^6,14,15
• Intralesional triamcinolone injections are considered standard of care. Adotama et al¹⁶ found that injecting ­triamcinolone into the deep dermis in the area of flat or papular AKN yielded better control of inflammation and decreased appearance of lesions compared with injecting individual lesions.
• For extensive AKN lesions that do not respond to ­less-invasive therapies, consider surgical techniques,^6,17 such as follicular unit excision¹⁸ and more extensive surgical excisions building on approaches from pioneers Drs. John Kenney and Harold Pierce.¹⁹ An innovative surgical approach for removal of large AKNs is the bat excision technique—wound shape resembles a bat in a spread-eagled position—with secondary intention healing with or without debridement and/or tension sutures. The resulting linear scar acts as a new posterior hair line.²⁰

Health disparity highlights

Access to a dermatologic or plastic surgeon with expertise in the surgical treatment of large AKNs may be challenging but is needed to reduce risk for recurrence and adverse events.

Close-cropped haircuts on the occipital scalp, which are particularly popular among men of African descent, increase the risk for AKN.⁵ Although this grooming style may be a personal preference, other hairstyles commonly worn by those with tightly coiled hair may be deemed “unprofessional” in society or the workplace,²¹ which leads to hairstyling practices that may increase the risk for AKN.

Acne keloidalis nuchae remains an understudied entity that adversely affects patients with skin of color.

CARLSBAD, CALIF. — After Arash Moradzadeh, MD, treated the first 100 consecutive patients in his practice with a 1726-nm laser (AviClear) following its Food and Drug Administration (FDA) clearance for the treatment of mild to severe acne vulgaris in March of 2022, 90% experienced clearance at 1 year.

“Combining the AviClear with medical therapy and energy-based devices provides the best outcomes,” Dr. Moradzadeh, who practices facial and plastic surgery in Beverly Hills, California, said at the Controversies & Conversations in Laser & Cosmetic Surgery annual symposium. “You have to do all 300 pulses per treatment, and you do need to use settings of 19.5-21.5 J/cm² to get a great result.”

After years of debate and disagreement, could an improved, more user-friendly version of iPLEDGE be on the horizon?

iPLEDGE, the Food and Drug Administration (FDA)–required Risk Evaluation and Mitigation Strategy (REMS) program launched in 2010, aims to manage the risks for the teratogenic acne drug isotretinoin and prevent fetal exposure. But it’s been dogged by issues and controversy, causing difficulties for patients and prescribers.

Late in 2023, there seemed to be a reason for optimism that improvements were coming. On November 30, 2023, the FDA informed isotretinoin manufacturers — known as the Isotretinoin Products Manufacturing Group (IPMG) — that they had 6 months to make five changes to the existing iPLEDGE REMS, addressing the controversies and potentially reducing glitches in the program and minimizing the burden of the program on patients, prescribers, and pharmacies — while maintaining safe use of the drug — and to submit their proposal by May 30, 2024.

The timeline for when an improved program might be in place remains unclear.

An FDA spokesperson, without confirming that the submission was submitted on time, recently said the review timeline once such a submission is received is generally 6 months.
 

‘Radio Silence’

No official FDA announcement has been made about the timeline, nor has information been forthcoming from the IPMG, and the silence has been frustrating for John S. Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, both in Boston, Massachusetts. He chairs the American Academy of Dermatology Association’s IPLEDGE Work Group, which works with both the FDA and IPMG.

Brigham and Women's Hospital

He began writing about issues with iPLEDGE about 4 years ago, when he and colleagues suggested, among other changes, simplifying the iPLEDGE contraception requirements in a paper published in the Journal of the American Academy of Dermatology.

In an interview, Dr. Barbieri expressed frustration about the lack of information on the status of the iPLEDGE changes. “We’ve been given no timeline [beyond the FDA’s May 30 deadline for the IPMG to respond] of what might happen when. We’ve asked what was submitted. No one will share it with us or tell us anything about it. It’s just radio silence.”

Dr. Barbieri is also frustrated at the lack of response from IPMG. Despite repeated requests to the group to include the dermatologists in the discussions, IPMG has repeatedly declined the help, he said.

IPMG appears to have no dedicated website. No response had been received to an email sent to an address attributed to the group asking if it would share the submission to the FDA.

Currently, isotretinoin, originally marketed as Accutane, is marketed under such brand names as Absorica, Absorica LD, Claravis, Amnesteem, Myorisan, and Zenatane.

Asked for specific information on the proposed changes, an FDA spokesperson said in an August 19 email that “the submission to the FDA from the isotretinoin manufacturers will be a major modification, and the review timeline is generally 6 months. Once approved, the isotretinoin manufacturers will need additional time to implement the changes.”

The spokesperson declined to provide additional information on the status of the IPMG proposal, to share the proposal itself, or to estimate the implementation period.


 

Reason for Hope?

In response to the comment that the review generally takes 6 months, Dr. Barbieri said it doesn’t give him much hope, adding that “any delay of implementing these reforms is a missed opportunity to improve the care of patients with acne.” He is also hopeful that the FDA will invite some public comment during the review period “so that stakeholders can share their feedback about the proposal to help guide FDA decision-making and ensure effective implementation.”
 

From Meeting to Mandate

The FDA order for the changes followed a joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee in March 2023 about the program requirements. It included feedback from patients and dermatologists and recommendations for changes, with a goal of reducing the burden of the program on patients, pharmacies, and prescribers without compromising patient safety.

The Five Requested Changes

In the November 30 letter, the FDA requested the following from the IPMG:

• Remove the requirement that pregnancy tests be performed in a specially certified lab (such as a Clinical Laboratory Improvement Amendments lab). This would enable the tests to be done in a clinic setting rather than sending patients to a separate lab.
• Allow prescribers the option of letting patients use home pregnancy tests during and after treatment, with steps in place to minimize falsification.
• Remove the waiting period requirement, known as the “19-day lockout,” for patients if they don’t obtain the isotretinoin from the pharmacy within the first 7-day prescription window. Before initiation of isotretinoin, a repeat confirmatory test must be done in a medical setting without any required waiting period.
• Revise the pregnancy registry requirement, removing the objective to document the outcome and associated collection of data for each pregnancy.
• Revise the requirement for prescribers to document patient counseling for those who can’t become pregnant from monthly counseling to counseling at enrollment only. Before each prescription is dispensed, the authorization must verify patient enrollment and prescriber certification. (In December 2021, a new, gender-neutral approach, approved by the FDA, was launched. It places potential patients into two risk categories — those who can become pregnant and those who cannot. Previously, there were three such categories: Females of reproductive potential, females not of reproductive potential, and males.)

Perspective on the Requested Changes

Of the requested changes, “really the most important is eliminating the request for monthly counseling for patients who cannot become pregnant,” Dr. Barbieri said. Because of that requirement, all patients need to have monthly visits with a dermatologist to get the medication refills, “and that creates a logistical barrier,” plus reducing time available for dermatologists to care for other patients with other dermatologic issues.

As for missing the 7-day prescription window, Dr. Barbieri said, in his experience, “it’s almost never the patient’s fault; it’s almost always an insurance problem.”

Dr. Barbieri reported no relevant conflicts of interest.

In response to the comment that the review generally takes 6 months, Dr. Barbieri said it doesn’t give him much hope, adding that “any delay of implementing these reforms is a missed opportunity to improve the care of patients with acne.” He is also hopeful that the FDA will invite some public comment during the review period “so that stakeholders can share their feedback about the proposal to help guide FDA decision-making and ensure effective implementation.”
 

From Meeting to Mandate

The FDA order for the changes followed a joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee in March 2023 about the program requirements. It included feedback from patients and dermatologists and recommendations for changes, with a goal of reducing the burden of the program on patients, pharmacies, and prescribers without compromising patient safety.

The Five Requested Changes

In the November 30 letter, the FDA requested the following from the IPMG:

• Remove the requirement that pregnancy tests be performed in a specially certified lab (such as a Clinical Laboratory Improvement Amendments lab). This would enable the tests to be done in a clinic setting rather than sending patients to a separate lab.
• Allow prescribers the option of letting patients use home pregnancy tests during and after treatment, with steps in place to minimize falsification.
• Remove the waiting period requirement, known as the “19-day lockout,” for patients if they don’t obtain the isotretinoin from the pharmacy within the first 7-day prescription window. Before initiation of isotretinoin, a repeat confirmatory test must be done in a medical setting without any required waiting period.
• Revise the pregnancy registry requirement, removing the objective to document the outcome and associated collection of data for each pregnancy.
• Revise the requirement for prescribers to document patient counseling for those who can’t become pregnant from monthly counseling to counseling at enrollment only. Before each prescription is dispensed, the authorization must verify patient enrollment and prescriber certification. (In December 2021, a new, gender-neutral approach, approved by the FDA, was launched. It places potential patients into two risk categories — those who can become pregnant and those who cannot. Previously, there were three such categories: Females of reproductive potential, females not of reproductive potential, and males.)

Perspective on the Requested Changes

Of the requested changes, “really the most important is eliminating the request for monthly counseling for patients who cannot become pregnant,” Dr. Barbieri said. Because of that requirement, all patients need to have monthly visits with a dermatologist to get the medication refills, “and that creates a logistical barrier,” plus reducing time available for dermatologists to care for other patients with other dermatologic issues.

As for missing the 7-day prescription window, Dr. Barbieri said, in his experience, “it’s almost never the patient’s fault; it’s almost always an insurance problem.”

Dr. Barbieri reported no relevant conflicts of interest.

Since the first Food and Drug Administration approval of a Janus kinase (JAK) inhibitor in 2011, the number of these medications available — and their treatment indications — have continued to grow. Prescribing physicians are familiar with the benefits and risks for these drugs, including higher risk for cardiac events and malignancy; however, one adverse effect may be overlooked, especially by specialties outside of dermatology: acne. Though less serious than some other side effects, JAK inhibitor–associated acne — JAKne, for short — can be a concern for patients.

“Your physical appearance and how you present yourself to the world is an important part of your self-confidence and living life on your own terms,” said Arash Mostaghimi, MD, the director of inpatient dermatology at Brigham and Women’s Hospital in Boston, Massachusetts. “I think letting people know about [JAKne] and then addressing it when it occurs should be a normal part of managing these medications.”
 

What Is JAKne?

JAKne generally looks like other kinds of acne, explained Janelle Nassim, MD, director of laser and cosmetic dermatology at the Indiana University School of Medicine, Indianapolis. “It can affect the same areas that typical acne affects, including the face, chest, back, neck, and upper shoulders.”

Though it appears like typical forms of acne, it is not clear what drives these skin eruptions in patients taking JAK inhibitors.

“We don’t understand the underlying pathophysiology,” Dr. Mostaghimi said. “It looks like acne, but we don’t know if the exact underlying inflammatory process is the same or if it’s different.”

In a 2023 systematic review of clinical studies, Dr. Mostaghimi and colleagues found that patients on any JAK inhibitor were nearly four times more likely to experience acne than patients who received placebo, but risk varied between medications. Patients taking JAK inhibitors for skin conditions had higher risk for acne than those given the medications for other indications. However, Dr. Mostaghimi thinks this finding is the result of selection bias.

Participants may not mention side effects like acne in trials for rheumatologic or gastrointestinal conditions, he said, unlike in trials for skin conditions. “Clinically, I’ve seen it in patients across every indication.”

Patients with a history of acne seem to be more likely to develop this side effect, though formal studies looking into risk factors are lacking. In Dr. Mostaghimi’s own clinical experience, JAKne is also more common in younger patients, but it can happen to anyone. “I’ve seen 70-year-olds develop acne — patients who’ve never had an issue their whole life — when they’re taking a JAK inhibitor.”

This issue also appears to be more common earlier in treatment, he added, and may improve over time as a patient continues with the medication.
 

How Do You Treat It?

“I think in other specialties, you will often feel awkward addressing skin conditions or pointing out acne,” Dr. Mostaghimi said. The most important steps are being aware of this potential side effect, and if you see it practice, to bring it up.

“Say: I’m noticing there’s some changes in your skin. Some patients on JAK inhibitors develop more acne. Have you noticed this? And if so, is this bothering you?”

Generally, JAKne is mild to moderate, explained Dr. Nassim, and if non-dermatologists are comfortable, they can prescribe a first-line topical regimen for patients. Dr. Mostaghimi recommends prescribing a clindamycin 1% lotion or gel. In addition, patients can use a benzoyl peroxide wash (4% or 10%) combined with a gentle retinoid, such as adapalene. (Both of these treatments are now available over the counter.)

In patients with scalp or hairline involvement, he often prescribes a ketoconazole 2% shampoo, which patients can use to wash their scalp, face, chest, and back in the shower.

If they aren’t responding to these initial treatments, then refer to a dermatologist for further assessment.

“Ultimately, referring to a dermatologist is the best course of action,” Dr. Nassim said. “I have had patients on JAK inhibitors who improved with topical acne treatments, and some that required more aggressive treatment with oral medications.”

Dr. Mostaghimi reported consulting fees from AbbVie, Concert Pharmaceuticals, Pfizer, and 3Derm Systems; research funding from Incyte, Aclaris Therapeutics, Eli Lilly, and Concert Pharmaceuticals; personal fees from Equillium, ASLAN Pharmaceuticals, ACOM, and Boehringer Ingelheim; and advisory board fees from Fig.1 Beauty, Eli Lilly, Pfizer, and Hims & Hers Health. Dr. Nassim had no relevant disclosures.

Potentially life-threatening cutaneous adverse drug reactions (cADRs) are associated with commonly prescribed oral antibiotics, according to a large, population-based, nested case-control study of older adults, spanning two decades.

The findings, published online in JAMA, “underscore the importance of judicious prescribing, with preferential use of antibiotics associated with a lower risk when clinically appropriate,” noted senior author David Juurlink, MD, PhD, professor of medicine; pediatrics; and health policy, management and evaluation at the University of Toronto, and head of the Clinical Pharmacology and Toxicology Division at Sunnybrook Health Sciences Centre, also in Toronto, Ontario, Canada, and coauthors.

“We hope our study raises awareness about the importance of drug allergy and gains support for future studies to improve drug allergy care,” lead author Erika Lee, MD, clinical immunology and allergy lecturer at the University of Toronto’s Drug Allergy Clinic, Sunnybrook Health Sciences Centre, said in an interview. “It is important to recognize symptoms and signs of a severe drug rash and promptly stop culprit drugs to prevent worsening reaction.”

Serious cADRs are “a group of rare but potentially life-threatening drug hypersensitivity reactions involving the skin and, frequently, internal organs,” the authors wrote. “Typically delayed in onset, these reactions include drug reaction with eosinophilia and systemic symptoms, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) — the most severe cADR, which has a reported mortality of 20%-40%,” they noted.

Speculation Without Data

Although it has been speculated that some oral antibiotics are more likely than others to be associated with serious cADRs, there have been no population-based studies examining this, they added.

The study included adults aged 66 years or older and used administrative health databases in Ontario, spanning from April 1, 2002, to March 31, 2022. Data on antibiotic use were taken from the Ontario Drug Benefit database. The Canadian Institute for Health Information (CIHI) National Ambulatory Care Reporting System was used to obtain data on emergency department (ED) visits for cADRs, while the CIHI Discharge Abstract Database was used to identify hospitalizations for cADRs. Finally, demographic information and outpatient healthcare utilization data were obtained from the Registered Persons Database and the Ontario Health Insurance Plan database, respectively.

A cohort of 21,758 older adults (median age, 75 years; 64.1% women) who had an ED visit or hospitalization for serious cADRs within 60 days of receiving antibiotic therapy was matched by age and sex with 87,025 antibiotic-treated controls who did not have a cutaneous reaction.

The median duration of antibiotic prescription was 7 days among cases and controls, and among the cases, the median latency period between antibiotic prescriptions and hospital visits for cADRs was 14 days. Most of the case patients went to the ED only (86.9%), and the rest were hospitalized.

The most commonly prescribed antibiotic class was penicillins (28.9%), followed by cephalosporins (18.2%), fluoroquinolones (16.5%), macrolides (14.8%), nitrofurantoin (8.6%), and sulfonamides (6.2%). Less commonly used antibiotics (“other” antibiotics) accounted for 6.9%.

Macrolide antibiotics were used as the reference because they are rarely associated with serious cADRs, noted the authors, and the multivariable analysis, adjusted for risk factors associated with serious cADRs, including malignancy, chronic liver disease, chronic kidney disease, and HIV.

After multivariable adjustment, relative to macrolides, sulfonamides were most strongly associated with serious cADRs (adjusted odds ratio [aOR], 2.9) but so were all other antibiotic classes, including cephalosporins (aOR, 2.6), “other” antibiotics (aOR, 2.3), nitrofurantoin (aOR, 2.2), penicillins (aOR, 1.4), and fluoroquinolones (aOR,1.3).

In the secondary analysis, the crude rate of ED visits or hospitalizations for cADRs was highest for cephalosporins (4.92 per 1000 prescriptions), followed by sulfonamides (3.22 per 1000 prescriptions). Among hospitalized patients, the median length of stay was 6 days, with 9.6% requiring transfer to a critical care unit and 5.3% dying in the hospital.
 

Hospitalizations, ED Visits Not Studied Previously

“Notably, the rate of antibiotic-associated serious cADRs leading to an ED visit or hospitalization has not been previously studied,” noted the authors. “We found that at least two hospital encounters for serious cADRs ensued for every 1000 antibiotic prescriptions. This rate is considerably higher than suggested by studies that examine only SJS/TEN and drug reaction with eosinophilia and systemic symptoms.”

Dr. Lee also emphasized the previously unreported findings about nitrofurantoin. “It is surprising to find that nitrofurantoin, a commonly prescribed antibiotic for urinary tract infection, is also associated with an increased risk of severe drug rash,” she said in an interview.

“This finding highlights a potential novel risk at a population-based level and should be further explored in other populations to verify this association,” the authors wrote.

Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security in Baltimore, Maryland, and a spokesperson for the Infectious Diseases Society of America, who was not involved in the study, agreed that the nitrofurantoin finding was surprising, but he was not surprised that sulfonamides were high on the list.

“The study reinforces that antibiotics are not benign medications to be dispensed injudiciously,” he said in an interview. “Antibiotics have risks, including serious skin reactions, as well as the fostering of antibiotic resistance. Clinicians should always first ask themselves if their patient actually merits an antibiotic and then assess what is the safest antibiotic for the purpose, bearing in mind that certain antibiotics are more likely to result in adverse reactions than others.”

The study was supported by the Canadian Institutes of Health Research. The study was conducted at ICES, which is funded in part by an annual grant from the Ontario Ministry of Health and Long-Term Care. One coauthor reported receiving compensation from the British Journal of Dermatology as reviewer and section editor, the American Academy of Dermatology as guidelines writer, Canadian Dermatology Today as manuscript writer, and the National Eczema Association and the Canadian Agency for Drugs and Technologies in Health as consultant; as well as receiving research grants to the coauthor’s institution from the National Eczema Association, Eczema Society of Canada, Canadian Dermatology Foundation, Canadian Institutes of Health Research, US National Institutes of Health, and PSI Foundation. Another coauthor reported receiving grants from AbbVie, Bausch Health, Celgene, Lilly, Incyte, Janssen, LEO Pharma, L’Oréal, Novartis, Organon, Pfizer, Sandoz, Amgen, and Boehringer Ingelheim; receiving payment or honoraria for speaking from Sanofi China; participating on advisory boards for LEO Pharma, Novartis, Sanofi, and Union Therapeutics; and receiving equipment donation from L’Oréal.

This rate is considerably higher than suggested by studies that examine only SJS/TEN and drug reaction with eosinophilia and systemic symptoms.”

Dr. Lee also emphasized the previously unreported findings about nitrofurantoin. “It is surprising to find that nitrofurantoin, a commonly prescribed antibiotic for urinary tract infection, is also associated with an increased risk of severe drug rash,” she said in an interview.

“This finding highlights a potential novel risk at a population-based level and should be further explored in other populations to verify this association,” the authors wrote.

Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security in Baltimore, Maryland, and a spokesperson for the Infectious Diseases Society of America, who was not involved in the study, agreed that the nitrofurantoin finding was surprising, but he was not surprised that sulfonamides were high on the list.

“The study reinforces that antibiotics are not benign medications to be dispensed injudiciously,” he said in an interview. “Antibiotics have risks, including serious skin reactions, as well as the fostering of antibiotic resistance. Clinicians should always first ask themselves if their patient actually merits an antibiotic and then assess what is the safest antibiotic for the purpose, bearing in mind that certain antibiotics are more likely to result in adverse reactions than others.”

The study was supported by the Canadian Institutes of Health Research. The study was conducted at ICES, which is funded in part by an annual grant from the Ontario Ministry of Health and Long-Term Care. One coauthor reported receiving compensation from the British Journal of Dermatology as reviewer and section editor, the American Academy of Dermatology as guidelines writer, Canadian Dermatology Today as manuscript writer, and the National Eczema Association and the Canadian Agency for Drugs and Technologies in Health as consultant; as well as receiving research grants to the coauthor’s institution from the National Eczema Association, Eczema Society of Canada, Canadian Dermatology Foundation, Canadian Institutes of Health Research, US National Institutes of Health, and PSI Foundation. Another coauthor reported receiving grants from AbbVie, Bausch Health, Celgene, Lilly, Incyte, Janssen, LEO Pharma, L’Oréal, Novartis, Organon, Pfizer, Sandoz, Amgen, and Boehringer Ingelheim; receiving payment or honoraria for speaking from Sanofi China; participating on advisory boards for LEO Pharma, Novartis, Sanofi, and Union Therapeutics; and receiving equipment donation from L’Oréal. Dr. Adalja reported no relevant disclosures.

Gluconolactone, 3,4,5-trihydroxy-6-(hydroxymethyl) oxan-2-one (C₆H₁₀O₆), is known to display antioxidant, moisturizing, and soothing activity as well as enhance skin barrier function and protect elastin fibers from UV-engendered damage.¹ This derivative of oxidized glucose lactone is present naturally in bread, cheese, fruit juices, honey, tofu, and wine, and is used as a food additive in Europe.^1,2 In dermatology, it is most often used in chemical peels.

Polyhydroxy acids (PHAs) were discovered about 3 decades ago to exert similar functions as alpha hydroxy acids without provoking sensory irritation reactions. Gluconolactone along with lactobionic acid were the identified PHAs and further characterized as delivering more humectant and moisturizing activity than alpha hydroxy acids and effective in combination with retinoic acid to treat adult acne and with retinyl acetate to confer antiaging benefits.³ It is typically added to products for its skin-conditioning qualities, resulting in smoother, brighter, more toned skin.⁴ This column focuses on recent studies using this bioactive agent for dermatologic purposes.
 

Split-Face Studies Show Various Benefits

In 2023, Jarząbek-Perz and colleagues conducted a split-face evaluation to assess the effects on various skin parameters (ie, hydration, pH, sebum, and transepidermal water loss [TEWL]) of gluconolactone and oxybrasion, compared with gluconolactone and microneedling. Twenty-one White women underwent a series of three split-face treatments at 1-week intervals. Chemical peels with 10% gluconolactone were performed on the whole face. The right side of the face was also treated with oxybrasion and the left with microneedle mesotherapy. Skin parameters were measured before the first and third treatments and 2 weeks following the final treatment. Photos were taken before and after the study. Both treatments resulted in improved hydration and reductions in sebum, pH, and TEWL. No statistically significant differences were noted between the treatment protocols. The researchers concluded that gluconolactone peels can be effectively combined with oxybrasion or microneedle mesotherapy to enhance skin hydration and to secure the hydrolipid barrier.⁵

Later that year, the same team evaluated pH, sebum levels, and TEWL before, during, and after several applications of 10% and 30% gluconolactone chemical peels in a split-face model in 16 female participants. The investigators conducted three procedures on both sides of the face, taking measurements on the forehead, periorbital area, on the cheek, and on the nose wing before, during, and 7 days after the final treatment. They found statistically significant improvements in sebum levels in the cheeks after the treatment series. Also, pH values were lower at each measurement site after each procedure. TEWL levels were significantly diminished around the eyes, as well as the left forehead and right cheek, with no significant discrepancy between gluconolactone concentrations. The researchers concluded that gluconolactone plays a major role in reducing cutaneous pH and TEWL and imparts a regulatory effect on sebum.¹

Two years earlier, Jarząbek-Perz and colleagues assessed skin moisture in a split-face model in 16 healthy women after the application of 10% and 30% gluconolactone. Investigators measured skin moisture before and after each of three treatments and a week after the final treatment from the forehead, periorbital area, and on the cheek. They observed no significant discrepancies between the 10% and 30% formulations, but a significant elevation in facial skin hydration was found to be promoted by gluconolactone. The investigators concluded that gluconolactone is an effective moisturizer for care of dry skin.⁶

Topical Formulation

In 2023, Zerbinati and colleagues determined that a gluconolactone-based lotion that they had begun testing 2 years earlier was safe and effective for dermatologic applications, with the noncomedogenic formulation found suitable as an antiaging agent, particularly as it treats aging-related pore dilatation.^7,8

Acne Treatment

In 2019, Kantikosum and colleagues conducted a double-blind, within-person comparative study to assess the efficacy of various cosmeceutical ingredients, including gluconolactone, glycolic acid, licochalcone A, and salicylic acid, combined with the acne treatment adapalene vs adapalene monotherapy for mild to moderate acne. Each of 25 subjects over 28 days applied a product mixed with 0.1% adapalene on one side of the face, and 0.1% adapalene alone on the other side of the face once nightly. The VISIA camera system spot score pointed to a statistically significant improvement on the combination sides. Differences in lesion reduction and severity were within acceptable margins, the authors reported. They concluded that the cosmeceutical combinations yielded similar benefits as adapalene alone, with the combination formulations decreasing acne complications.⁹

Potential Use as an Antifibrotic Agent

Baumann Cosmetic & Research Institute

In 2018, Jayamani and colleagues investigated the antifibrotic characteristics of glucono-delta-lactone, a known acidifier, to ascertain if it could directly suppress collagen fibrils or even cause them to disintegrate. The researchers noted that collagen fibrillation is pH dependent, and that glucono-delta-lactone was found to exert a concentration-dependent suppression of fibrils and disintegration of preformed collagen fibrils with the antifibrotic function of the compound ascribed to its capacity to decrease pH. Further, glucono-delta-lactone appeared to emerge as an ideal antifibrotic agent as it left intact the triple helical structure of collagen after treatment. The investigators concluded that glucono-delta-lactone provides the foundation for developing antifibrotic agents intended to treat disorders characterized by collagen deposition.¹⁰

Conclusion

Gluconolactone emerged in the 1990s as a PHA useful in skin peels as an alternative to alpha hydroxy acids because of its nonirritating qualities. Since then, its soothing, hydrating, and, in particular, antiacne and antiaging qualities have become established. Wider applications of this versatile agent for dermatologic purposes are likely to be further investigated.

TORONTO — Dermatologists should prescribe emergency contraception (EC) to adolescent patients being treated with isotretinoin for acne.

That was one of the main messages from Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, who discussed hormonal therapies for pediatric acne at the annual meeting of the Society for Pediatric Dermatology.

Many doctors are reluctant to prescribe EC, which refers to contraceptive methods used to prevent unintended pregnancy after unprotected sexual intercourse or contraceptive failure, whether that’s from discomfort with EC or lack of training, Dr. Zaenglein said in an interview.

Isotretinoin, a retinoid marketed as Accutane and other brand names, is an effective treatment for acne but carries serious teratogenicity risks; the iPLEDGE Risk Evaluation and Mitigation Strategy is designed to manage this risk and minimize fetal exposure. Yet from 2011 to 2017, 210-310 pregnancies per year were reported to the Food and Drug Administration, according to a 2019 study.

There is a knowledge gap regarding EC among dermatologists who prescribe isotretinoin, which “is perpetuated by the iPLEDGE program because it is inadequate in guiding clinicians or educating patients about the use of EC,” Dr. Zaenglein and colleagues wrote in a recently published viewpoint on EC prescribing in patients on isotretinoin.

Types of EC include oral levonorgestrel (plan B), available over the counter; oral ulipristal acetate (ella), which requires a prescription; and the copper/hormonal intrauterine device.

Not all teens taking isotretinoin can be trusted to be sexually abstinent. Dr. Zaenglein cited research showing 39% of female high school students have had sexual relations. “In my opinion, these patients should have emergency contraception prescribed to them as a backup,” she said.

Dr. Zaenglein believes there’s a fair amount of “misunderstanding” about EC, with many people thinking it’s an abortion pill. “It’s a totally different medicine. This is contraception; if you’re pregnant, it’s not going to affect your fetus.”

Outgoing SPD President Sheilagh Maguiness, MD, professor of dermatology and pediatrics, University of Minnesota, Minneapolis, agreed that Dr. Zaenglein raised an important issue. “She has identified a practice gap and a knowledge gap that we need to address,” she said in an interview.

When discussing contraception with female patients taking isotretinoin, assume they’re sexually active or could be, Dr. Zaenglein told meeting attendees. Be explicit about the risks to the fetus and consider their past compliance.
 

Complex Disorder

During her presentation, Dr. Zaenglein described acne as a “very complex, multifactorial inflammatory disorder” of the skin. It involves four steps: Increased sebum production, hyperkeratinization, Cutibacterium acnes, and inflammation. External factors such as diet, genes, and the environment play a role.

“But at the heart of all of it is androgens; if you didn’t have androgens, you wouldn’t have acne.” That’s why some acne treatments block androgen receptors.

Clinicians are increasingly using one such therapy, spironolactone, to treat acne in female adolescents. Dr. Zaenglein referred to a Mayo Clinic study of 80 patients (mean age, 19 years), who had moderate to severe acne treated with a mean dose of 100 mg/day, that found 80% had improvement with a favorable side effect profile. This included nearly 23% who had a complete response (90% or more) and 36% who had a partial response (more than 50%); 20% had no response.

However, response rates are higher in adults, said Dr. Zaenglein, noting that spironolactone works “much better” in adult women.

Side effects of spironolactone can include menstrual disturbances, breast enlargement and tenderness, and premenstrual syndrome–like symptoms.

Dermatologists should also consider combined oral contraceptives (COCs) in their adolescent patients with acne. These have an estrogen component as well as a progestin component.

They have proven effectiveness for acne in adolescents, yet a US survey of 170 dermatology residents found only 60% felt comfortable prescribing them to healthy adolescents. The survey also found only 62% of respondents felt adequately trained on the efficacy of COCs, and 42% felt adequately trained on their safety.

Contraindications for COCs include thrombosis, migraine with aura, lupus, seizures, and hypertension. Complex valvular heart disease and liver tumors also need to be ruled out, said Dr. Zaenglein. One of the “newer concerns” with COCs is depression. “There’s biological plausibility because, obviously, hormones impact the brain.”
 

Preventing Drug Interactions

Before prescribing hormonal therapy, clinicians should carry out an acne assessment, aimed in part at preventing drug interactions. “The one we mostly have to watch out for is rifampin,” an antibiotic that could interact with COCs, said Dr. Zaenglein.

The herbal supplement St John’s Wort can reduce the efficacy of COCs. “You also want to make sure that they’re not on any medicines that will increase potassium, such as ACE inhibitors,” said Dr. Zaenglein. But tetracyclines, ampicillin, or metronidazole are usually “all okay” when combined with COCs.

It’s important to get baseline blood pressure levels and to check these along with weight on a regular basis, she added.

Always Consider PCOS

Before starting hormonal therapy, she advises dermatologists to “always consider” polycystic ovary syndrome (PCOS), a condition that’s “probably much underdiagnosed.” Acne is common in adolescents with PCOS. She suggests using a PCOS checklist, a reminder to ask about irregular periods, hirsutism, signs of insulin resistance such as increased body mass index, a history of premature adrenarche, and a family history of PCOS, said Dr. Zaenglein, noting that a person with a sibling who has PCOS has about a 40% chance of developing the condition.

“We play an important role in getting kids diagnosed at an early age so that we can make interventions because the impact of the metabolic syndrome can have lifelong effects on their cardiovascular system, as well as infertility.”

Dr. Zaenglein is a member of the American Academy of Dermatology (AAD) Acne Guidelines work group, the immediate past president of the American Acne and Rosacea Society, a member of the AAD iPLEDGE work group, co–editor in chief of Pediatric Dermatology, an advisory board member of Ortho Dermatologics, and a consultant for Church & Dwight. Dr. Maguiness had no relevant conflicts of interest.

There is a knowledge gap regarding EC among dermatologists who prescribe isotretinoin, which “is perpetuated by the iPLEDGE program because it is inadequate in guiding clinicians or educating patients about the use of EC,” Dr. Zaenglein and colleagues wrote in a recently published viewpoint on EC prescribing in patients on isotretinoin.

Types of EC include oral levonorgestrel (plan B), available over the counter; oral ulipristal acetate (ella), which requires a prescription; and the copper/hormonal intrauterine device.

Not all teens taking isotretinoin can be trusted to be sexually abstinent. Dr. Zaenglein cited research showing 39% of female high school students have had sexual relations. “In my opinion, these patients should have emergency contraception prescribed to them as a backup,” she said.

Dr. Zaenglein believes there’s a fair amount of “misunderstanding” about EC, with many people thinking it’s an abortion pill. “It’s a totally different medicine. This is contraception; if you’re pregnant, it’s not going to affect your fetus.”

Outgoing SPD President Sheilagh Maguiness, MD, professor of dermatology and pediatrics, University of Minnesota, Minneapolis, agreed that Dr. Zaenglein raised an important issue. “She has identified a practice gap and a knowledge gap that we need to address,” she said in an interview.

When discussing contraception with female patients taking isotretinoin, assume they’re sexually active or could be, Dr. Zaenglein told meeting attendees. Be explicit about the risks to the fetus and consider their past compliance.
 

Complex Disorder

During her presentation, Dr. Zaenglein described acne as a “very complex, multifactorial inflammatory disorder” of the skin. It involves four steps: Increased sebum production, hyperkeratinization, Cutibacterium acnes, and inflammation. External factors such as diet, genes, and the environment play a role.

“But at the heart of all of it is androgens; if you didn’t have androgens, you wouldn’t have acne.” That’s why some acne treatments block androgen receptors.

Clinicians are increasingly using one such therapy, spironolactone, to treat acne in female adolescents. Dr. Zaenglein referred to a Mayo Clinic study of 80 patients (mean age, 19 years), who had moderate to severe acne treated with a mean dose of 100 mg/day, that found 80% had improvement with a favorable side effect profile. This included nearly 23% who had a complete response (90% or more) and 36% who had a partial response (more than 50%); 20% had no response.

However, response rates are higher in adults, said Dr. Zaenglein, noting that spironolactone works “much better” in adult women.

Side effects of spironolactone can include menstrual disturbances, breast enlargement and tenderness, and premenstrual syndrome–like symptoms.

Dermatologists should also consider combined oral contraceptives (COCs) in their adolescent patients with acne. These have an estrogen component as well as a progestin component.

They have proven effectiveness for acne in adolescents, yet a US survey of 170 dermatology residents found only 60% felt comfortable prescribing them to healthy adolescents. The survey also found only 62% of respondents felt adequately trained on the efficacy of COCs, and 42% felt adequately trained on their safety.

Contraindications for COCs include thrombosis, migraine with aura, lupus, seizures, and hypertension. Complex valvular heart disease and liver tumors also need to be ruled out, said Dr. Zaenglein. One of the “newer concerns” with COCs is depression. “There’s biological plausibility because, obviously, hormones impact the brain.”
 

Preventing Drug Interactions

Before prescribing hormonal therapy, clinicians should carry out an acne assessment, aimed in part at preventing drug interactions. “The one we mostly have to watch out for is rifampin,” an antibiotic that could interact with COCs, said Dr. Zaenglein.

The herbal supplement St John’s Wort can reduce the efficacy of COCs. “You also want to make sure that they’re not on any medicines that will increase potassium, such as ACE inhibitors,” said Dr. Zaenglein. But tetracyclines, ampicillin, or metronidazole are usually “all okay” when combined with COCs.

It’s important to get baseline blood pressure levels and to check these along with weight on a regular basis, she added.

Always Consider PCOS

Before starting hormonal therapy, she advises dermatologists to “always consider” polycystic ovary syndrome (PCOS), a condition that’s “probably much underdiagnosed.” Acne is common in adolescents with PCOS. She suggests using a PCOS checklist, a reminder to ask about irregular periods, hirsutism, signs of insulin resistance such as increased body mass index, a history of premature adrenarche, and a family history of PCOS, said Dr. Zaenglein, noting that a person with a sibling who has PCOS has about a 40% chance of developing the condition.

“We play an important role in getting kids diagnosed at an early age so that we can make interventions because the impact of the metabolic syndrome can have lifelong effects on their cardiovascular system, as well as infertility.”

Dr. Zaenglein is a member of the American Academy of Dermatology (AAD) Acne Guidelines work group, the immediate past president of the American Acne and Rosacea Society, a member of the AAD iPLEDGE work group, co–editor in chief of Pediatric Dermatology, an advisory board member of Ortho Dermatologics, and a consultant for Church & Dwight. Dr. Maguiness had no relevant conflicts of interest.

TORONTO — Dermatologists should prescribe emergency contraception (EC) to adolescent patients being treated with isotretinoin for acne.

That was one of the main messages from Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, who discussed hormonal therapies for pediatric acne at the annual meeting of the Society for Pediatric Dermatology.

Many doctors are reluctant to prescribe EC, which refers to contraceptive methods used to prevent unintended pregnancy after unprotected sexual intercourse or contraceptive failure, whether that’s from discomfort with EC or lack of training, Dr. Zaenglein said in an interview.

Isotretinoin, a retinoid marketed as Accutane and other brand names, is an effective treatment for acne but carries serious teratogenicity risks; the iPLEDGE Risk Evaluation and Mitigation Strategy is designed to manage this risk and minimize fetal exposure. Yet from 2011 to 2017, 210-310 pregnancies per year were reported to the Food and Drug Administration, according to a 2019 study.

Two new studies focusing on the safety of benzoyl peroxide (BP)–containing acne products with typical everyday use found no reason for concern about either high blood levels of benzene, a breakdown product of BP, or cancer risk.

Earlier this year, controversy erupted after an independent lab Valisure petitioned the US Food and Drug Administration (FDA) to recall acne products with BP because it found extremely high levels of the carcinogen benzene. In the research, the lab directors contended that the products can form over 800 times the “conditionally restricted” FDA concentration limit of 2 parts per million (ppm) of benzene, with both prescription and over-the-counter (OTC) products affected. The issue, according to the lab’s report, is one of degradation, not contamination; BP can decompose into benzene. Exposures to benzene have been linked with a higher risk for leukemia and other blood cancers.

(“Conditionally restricted” means that the maximum of 2 ppm only applies to a drug product in which the use of benzene is unavoidable in order to produce a drug product with a significant therapeutic advance, according to FDA guidance.)

Critics of the report questioned the method used to test the products, calling for more “real-world” use data, and said the temperature used may not be what is expected with everyday use.

Now, both new studies are reassuring about the safety of the products, John Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, said in a telephone interview. He was a coauthor of both studies. A leading dermatologist not involved in the new research reviewed the findings and agreed.

Under high temperatures, or over a long period, BP can decompose to benzene, a colorless, flammable liquid with a sweet odor. Benzene is formed from natural processes such as forest fires and volcanoes, according to the American Cancer Society, and is found in the air, cigarette smoke, some foods (at low levels), and contaminated drinking water. It’s one of the 20 widely used chemicals involved in making plastics, resins, detergents, and pesticides, among other products.

In the study evaluating blood levels, the researchers matched 14 people who used BP products currently with 65 controls who did not. Five (36%) of those using the products had detectable blood levels; 21 (32%) of those who did not use them did. There was no association between BP exposure and detectable blood benzene levels (odds ratio, 1.12; P = .80).

In the larger study, the researchers used the TriNetX US Collaborative Network database, comparing more than 27,000 patients treated with BP products for acne with more than 27,000 patients aged 12-40 years who had a diagnosis of nevus or seborrheic keratosis with no exposure to prescribed BP or any diagnosis of acne, hidradenitis suppurativa, or rosacea. The researchers looked at the database over the subsequent 10 years to determine the risk for either blood cancers or internal malignancies.

Compared with patients diagnosed with nevus or seborrheic keratosis, those with acne treated with BP had no significant difference in the risk for lymphoma (hazard ratio [HR], 1.00), leukemia (HR, 0.91), any lymphoma or leukemia (HR, 1.04), and internal malignancies (HR, 0.93).

The findings suggest no increased risk for malignancy, the researchers said, although they acknowledged study limitations, such as possible misclassification of BP exposure due to OTC availability and other issues.

Value of BP Treatments

BP is the “go-to” acne treatment, as Dr. Barbieri pointed out. “It’s probably the number one treatment for acne,” and there’s no substitute for it and it’s one of the most effective topical acne treatments, he noted.

Despite the reassuring findings, Dr. Barbieri repeated advice he gave soon after the Valisure report was released. Use common sense and don’t store BP-containing products in hot cars or other hot environments. In warmer climates, refrigeration could be considered, he said. Discard old products. Manufacturers should use cold-chain storage from the manufacturing site to retail or pharmacy sale sites, he added.
 

FDA and Citizen Petition Status

Asked about the status of the petition from Valisure, an FDA spokesperson said: “The FDA does not comment on the status of pending petitions.”

Dr. Barbieri and Dr. Lim had no relevant disclosures. There were no funding sources for either of the two studies.

Prescriptions for isotretinoin may be influenced by patient demographics, medical comorbidities, and drug safety programs.^1,2 In 1982, isotretinoin was approved by the US Food and Drug Administration for treatment of severe recalcitrant nodulocystic acne that is nonresponsive to conventional therapies such as antibiotics; however, prescriber beliefs regarding the necessity of oral antibiotic failure before isotretinoin is prescribed may be influenced by the provider’s generational age.³ Currently, there is a knowledge gap regarding the impact of provider characteristics, including the year providers completed training, on isotretinoin utilization. The aim of our cross-sectional study was to characterize generational isotretinoin prescribing habits in a large-scale midwestern private practice dermatology group.

Modernizing Medicine (https://www.modmed.com), an electronic medical record software, was queried for all encounters that included both an International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis code L70.0 (acne vulgaris) and a medication prescription from May 2021 to May 2022. Data were collected from a large private practice group with locations across the state of Ohio. Exclusion criteria included provider-patient prescription pairs that included non–acne medication prescriptions, patients seen by multiple providers, and providers who treated fewer than 5 patients with acne during the study period. A mixed-effect multiple logistic regression was performed to analyze whether a patient was ever prescribed isotretinoin, adjusting for individual prescriber, prescriber generation (millennial [1981–1996], Generation X [1965–1980], and baby boomer [1946–1964]),⁴ and patient sex; spironolactone and oral antibiotic prescriptions during the study period were included as additional covariates in a subsequent post hoc analysis. This study utilized data that was fully deidentified in accordance with the US Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule. Approval from an institutional review board was not required.

A total of 18,089 provider-patient prescription pairs were included in our analysis (Table). In our most robust model, female patients were significantly less likely to receive isotretinoin compared with male patients (adjusted OR [aOR], 0.394; P<.01). Millennial providers were significantly more likely to utilize isotretinoin in patients who did not receive antibiotics compared with patients who did receive antibiotics (aOR, 1.693; P<.01). When compared with both Generation X and baby boomers, millennial providers were more likely to prescribe isotretinoin in patients who received antibiotics (aOR, 2.227 [P=.02] and 3.638 [P<.01], respectively).

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.¹ In this article, the following terms are used as defined below:

• The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
• The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.

The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.² The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.² Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.

Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.³ At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.28⁴—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).⁴

There currently are several different GAP models among the military branches.⁵ Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.⁵

Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.

Benefits of Gender-Affirming Care

Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.⁶ It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.^7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.¹ Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.^1,7-9

The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.¹

Aesthetic Procedures in Gender-Affirming Care

Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.

Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.

Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.¹⁰ The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,¹¹ while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.

Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.

Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.

Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.¹² Reducing fat around the axillae also can help promote a more masculine upper torso.¹³ The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.

Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.^14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.^14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.¹⁶

Another novel treatment for unwanted hair is eflor­nithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.¹⁷

Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.

Management of Hormonal Adverse Effects

Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.¹⁸ Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.¹

Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.¹ Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.

If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,¹⁹ some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.^20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.¹ If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.

Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.²² This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.

Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al¹ recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.¹ Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.

Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.¹ Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.¹

There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair transplantation. Although this procedure gives dramatic results, it typically is performed by a specialized dermatologist, is not covered by insurance, and can cost up to tens of thousands of dollars out-of-pocket. Patients typically require continuous medical management of AGA even after the procedure. Examples of treatment modalities with uncertain supporting evidence are platelet-rich plasma injections, laser combs or hats, and microneedling. Additionally, clascoterone is a topical antiandrogen currently approved for acne, but it is under investigation for the treatment of AGA and may become an additional nonsystemic medication available for AGA in the future.²³

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.^24,25

Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.

Future Directions

The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.

Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.²⁹

Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.^30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.

Final Thoughts

Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.¹ In this article, the following terms are used as defined below:

• The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
• The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens.

Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.

Future Directions

The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.

Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.²⁹

Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.^30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.

Final Thoughts

Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.¹ In this article, the following terms are used as defined below:

• The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
• The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.

The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.² The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.² Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.

Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.³ At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.28⁴—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).⁴

There currently are several different GAP models among the military branches.⁵ Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.⁵

Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.

Benefits of Gender-Affirming Care

Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.⁶ It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.^7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.¹ Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.^1,7-9

The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.¹

Aesthetic Procedures in Gender-Affirming Care

Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.

Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.

Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.¹⁰ The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,¹¹ while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.

Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.

Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.

Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.¹² Reducing fat around the axillae also can help promote a more masculine upper torso.¹³ The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.

Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.^14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.^14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.¹⁶

Another novel treatment for unwanted hair is eflor­nithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.¹⁷

Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.

Management of Hormonal Adverse Effects

Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.¹⁸ Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.¹

Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.¹ Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.

If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,¹⁹ some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.^20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.¹ If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.

Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.²² This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.

Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al¹ recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.¹ Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.

Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.¹ Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.¹

There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair transplantation. Although this procedure gives dramatic results, it typically is performed by a specialized dermatologist, is not covered by insurance, and can cost up to tens of thousands of dollars out-of-pocket. Patients typically require continuous medical management of AGA even after the procedure. Examples of treatment modalities with uncertain supporting evidence are platelet-rich plasma injections, laser combs or hats, and microneedling. Additionally, clascoterone is a topical antiandrogen currently approved for acne, but it is under investigation for the treatment of AGA and may become an additional nonsystemic medication available for AGA in the future.²³

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.^24,25

Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.

Future Directions

The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.

Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.²⁹

Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.^30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.

Final Thoughts

Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.
