Yes, testosterone replacement therapy can cause acne, and it is the most commonly reported skin side effect of treatment. A 2026 scoping review in Sexual Medicine Reviews found acne in 0.6% to 9.1% of men on TRT, with injectable formulations producing higher rates than topical or oral ones. Most cases are mild, and almost none require stopping therapy.
The short version
Extra testosterone tells your oil glands to make more sebum, and more sebum means more clogged pores. Breakouts usually turn up on the lower face, chest, shoulders and back, often within the first several months, and they tend to be more stubborn than the acne you had at seventeen. A consistent salicylic-acid routine handles most of it without touching your protocol.
Why does testosterone therapy cause breakouts?
Testosterone drives sebum production. The American Academy of Dermatology explains that raising testosterone triggers the skin to produce more of that oil, which clogs pores and can set off inflammation. It is the same mechanism behind teenage acne, arriving at oil glands that were perfectly content a month ago. We have covered the broader version of this in our explainer on which hormones cause acne. TRT simply makes the hormone signal deliberate and dose-dependent.
How common is TRT acne, really?
Less common than gym forums suggest. The 2026 review pooled ten studies published between 2006 and 2025 and landed on that 0.6% to 9.1% range, meaning a minority of men either way. Itching was reported in up to 10% of participants, and rashes or unusual hair growth in up to 5.3%. Delivery method mattered: injections produced more acne and more systemic skin reactions than gels, patches or pills. This is worth knowing now because more men are on therapy than at any point in over a decade. Epic Research data puts the share of U.S. male patients prescribed testosterone at 0.95% in mid-2026, up from a low of 0.64% in 2021.
Where on the body does TRT acne show up?
The lower third of the face, the chest, the upper arms and the back, according to the AAD. That matches what most men on therapy describe: jawline and neck first, then shoulders and upper back. The body part is what catches guys off guard, because they have a face routine and nothing below the collar. Sweat left sitting on skin after a lift compounds it, which we get into in our guide to sweat and acne for athletes.
When does it start, and how long does it last?
Often within the first few months, though the AAD notes hormonal acne can appear any time within the first two years of starting testosterone. It also tends to be more persistent than ordinary hormonal acne, which means it needs a longer run of consistent care rather than a frantic week of spot treatment. Give any routine eight to twelve weeks before you decide whether it is working.
What routine actually handles it?
Salicylic acid, twice a day, every day, with no days off. Salicylic acid is oil-soluble, so it gets down into the pore where the excess sebum is actually sitting, which is exactly the problem TRT creates. That is the logic behind Level 1: The TiegeClear ACNE Essentials Routine — it pairs SAL ACID WASH, a salicylic-acid cleanser, with ACNE SERUM, a treatment moisturizer that keeps skin hydrated while it works. The pairing matters more than either piece alone. Acne products are drying, and skin that gets stripped tends to answer by making more oil, which is the opposite of what you want here. Level 1 is the right starting point for most men dealing with new breakouts on therapy; if your skin needs more, the TiegeClear line steps up from there.
The chest and back need their own answer, since a face wash never reaches them. ACNE ALL-OVER BODY SPRAY exists for the spots your hands cannot comfortably get to, which for most men is the middle of the back. Use it after showering, not instead of showering.
Do you have to stop TRT to clear your skin?
Almost certainly not. The AAD states plainly that patients do not need to discontinue testosterone therapy to treat acne successfully. For mild cases, it points to over-the-counter products containing adapalene, benzoyl peroxide or salicylic acid. Moderate to severe cases may call for prescription treatment, which is a conversation with a dermatologist rather than a decision to make alone. If your acne is cystic, painful or scarring, skip the self-experimentation and book the appointment.
Frequently asked questions
Will lowering my dose clear it up?
It might, since the effect is dose-related, but that is your prescriber's call and not a skincare decision. Most men get their skin under control without changing their protocol at all, which is the better order of operations: fix the routine first, then talk doses only if the routine fails.
Is TRT acne different from the acne I had as a teenager?
Same mechanism, different timeline. Teenage acne usually fades as hormones settle; acne on therapy persists as long as the hormone signal does, so it responds to consistency rather than to waiting it out.
Does scrubbing harder help?
No, and it reliably backfires. The AAD specifically warns against practices that irritate skin, scrubbing included. Inflamed skin looks worse and heals slower. Gentle cleansing twice a day beats aggressive cleansing once.
Do topical testosterone gels cause less acne than injections?
The review found lower rates of acne and systemic skin reactions with topical and oral preparations than with injectables. That is an observation across studies, not a recommendation, and switching delivery methods is a medical decision.
How long before a new routine shows results?
Plan on eight to twelve weeks of daily use before judging it. Skin cell turnover takes about a month, and acne that is already forming under the surface will still surface for a few weeks after you start.
