From the Guidelines
No, it is not safe to use testosterone gel on the face for facial hair growth. Testosterone gel (such as AndroGel, Testim, or Fortesta) is specifically designed for application on the shoulders, upper arms, or abdomen—never the face. Using it on the face can cause serious side effects including excessive absorption leading to hormonal imbalances, skin irritation, acne, and unwanted hair growth in adjacent areas. Additionally, the gel can transfer to others through skin contact, potentially causing masculinization effects in women and children, as noted in the AUA guideline on testosterone deficiency 1. Testosterone is a controlled substance that requires a prescription and medical supervision for legitimate medical conditions like hypogonadism. For those seeking facial hair growth, safer alternatives include minoxidil (Rogaine), which is FDA-approved for hair growth, proper nutrition, adequate sleep, and consulting with a dermatologist about appropriate treatments. Hormonal treatments should only be used under medical supervision for diagnosed conditions, not for cosmetic purposes, as emphasized in the American College of Physicians' clinical guideline on testosterone treatment in adult men with age-related low testosterone 1. The potential risks and benefits of testosterone treatment are also discussed in the evidence report for a clinical practice guideline by the American College of Physicians 1. It is essential to prioritize the safety and well-being of individuals, particularly women and children, who may be inadvertently exposed to testosterone gel, and to promote evidence-based practices in the use of hormonal treatments.
From the Research
Safety of Testosterone Gel on Face for Facial Hair Growth
- The use of testosterone gel on the face for facial hair growth has been studied in various contexts, including in individuals with beta-thalassemia major 2 and as part of gender-affirming hormone therapy.
- A study published in 2007 found that 2.5% testosterone gel was effective and well-tolerated in inducing the transformation of terminal hairs in the beard area of thalassemic males 2.
- However, the safety and efficacy of using testosterone gel on the face for facial hair growth in the general population is not well-established, and more research is needed to fully understand its effects.
Alternative Treatments for Facial Hair Growth
- Minoxidil, a topical medication, has been shown to be effective in promoting facial hair growth in individuals with androgenetic alopecia and in transgender males 3, 4.
- A study published in 2021 found that minoxidil was effective in promoting facial hair growth in a 17-year-old trans male who was unable to start testosterone therapy 3.
- Another study published in 2024 found that topical minoxidil was effective in enhancing beard growth in a group of transgender assigned female at birth individuals on gender-affirming hormone therapy 4.
Considerations for Testosterone Replacement Therapy
- Testosterone replacement therapy (TRT) is a medical treatment that involves the use of exogenous testosterone to treat hypogonadism in men 5.
- TRT is not without risks and side effects, and patients should be closely monitored while receiving this therapy 5.
- The use of testosterone gel on the face for facial hair growth may be considered as part of TRT, but patients should be aware of the potential risks and benefits and discuss their individual needs and goals with their healthcare provider.
