Testosterone therapy and acne breakouts: what the evidence says

What did @brendaunfiltered actually say?

Brenda says she self-administers testosterone injections as part of hormone replacement therapy and credits it with better energy, libido, and muscle support. Her main complaint: "the appearance of zits that I used to never get." She shows the camera several active breakouts and calls acne "the price to pay to feel good." This is a personal, anecdotal account, not a medical claim, and she is not prescribing anything to her audience. That context matters when evaluating it.

She is not overstating the benefits, inventing side effects, or selling anything in this clip. She is describing a real, documented phenomenon and asking her community for help managing it. That is actually a pretty responsible way to use social media health content, even if the framing is casual.

Does the science back this up?

Yes, substantially. Acne is one of the most consistently reported side effects of exogenous androgen use, including testosterone therapy in women. The mechanism is well understood: androgens stimulate sebaceous gland activity, increase sebum production, and alter follicular keratinization, all of which create conditions that favor acne-causing bacteria like Cutibacterium acnes.

A 2019 review by Yeung et al. in the Journal of the American Academy of Dermatology confirmed that androgen-driven acne is a recognized clinical entity, distinct from typical adolescent acne, and often requires targeted treatment. Research in transgender men on testosterone therapy has also documented acne as one of the most common early side effects, with prevalence estimates ranging from 30 to 40 percent in some cohorts (Turrion-Merino et al., 2015, Journal of the European Academy of Dermatology and Venereology). Brenda's experience is not unusual, and the biology behind it is solid.

What did they get wrong, or right?

Brenda got the core observation right. Testosterone can and does cause acne, especially in people who were not previously prone to breakouts. What she did not explain, understandably for a casual TikTok, is that acne severity often correlates with dosing, administration method, and conversion to dihydrotestosterone (DHT), the more potent androgen that has stronger effects on sebaceous glands.

She also frames acne as an unavoidable trade-off, "the price to pay." That framing deserves a gentle push back. Acne from testosterone therapy is common but not untreatable. Topical retinoids, benzoyl peroxide, and in some cases low-dose oral options discussed with a prescribing clinician can meaningfully reduce breakouts without requiring someone to stop therapy. Calling it simply "the price" could discourage people from seeking management options that actually work. That is not a factual error, but it is incomplete in a way that could affect real decisions.

What should you actually know?

If you are on testosterone therapy and developing acne, a few things are worth understanding before writing it off as inevitable.

• Acne from testosterone is androgen-driven, which means it may respond differently to standard over-the-counter products compared to hormonal acne from other causes. A dermatologist familiar with hormone-related acne is worth consulting.
• Injection timing can matter. Testosterone levels spike shortly after an injection and then decline. Some clinicians note that acne can worsen around peak levels. This is worth discussing with whoever manages your hormone therapy.
• DHT conversion plays a role. Some individuals convert more testosterone to DHT, which is more potent at the sebaceous gland. This is not something you can observe at home, but it can influence which treatments work.
• Topical tretinoin, a retinoid, has solid evidence for inflammatory acne and is commonly used alongside hormone therapy. It requires a prescription and a conversation with a clinician, not a TikTok comment.
• Stopping testosterone is not the only option if acne is bothersome. Managed correctly, many people achieve significant improvement while staying on therapy.

Brenda's video is honest and relatable. But anyone using her experience as a roadmap for their own care should also loop in a dermatologist or their prescribing provider before assuming acne is just something they have to tolerate.
