Acne is one of the most common side effects men notice after starting testosterone replacement therapy (TRT). Breakouts can appear on the face, but many men notice them most on the back, shoulders, and chest. The good news is that TRT-related acne is usually manageable with the right skincare, medical treatment when needed, and adjustments to the TRT plan itself.
This guide explains why TRT can cause acne, how to prevent and treat it, when prescription options such as isotretinoin (Accutane) come into play, and when to talk with your provider about your testosterone regimen.
Why Does TRT Cause Acne?
Testosterone and its more potent derivative, dihydrotestosterone (DHT), stimulate the skin’s sebaceous (oil) glands. More oil, combined with dead skin cells, can clog pores. Clogged pores create an environment where acne-associated bacteria (Cutibacterium acnes) thrive, leading to inflammation, whiteheads, blackheads, and deeper bumps.
Not every man on TRT develops acne. Risk tends to be higher if you:
- Had acne as a teenager or have a family history of acne
- Recently started TRT or had a dose increase
- Have large swings in testosterone levels between doses
- Have testosterone levels above your target range
- Sweat heavily, wear tight or synthetic clothing, or stay in workout clothes after exercise
For many men, breakouts are most noticeable in the first few months of treatment and may improve as levels stabilize. Persistent or severe acne deserves a closer look at both your skin care and your TRT plan.
Back, Chest, and Face Acne on TRT
The back, shoulders, and chest have a high density of oil glands, which is why “bacne” and chest acne are common on TRT. Body acne can be harder to reach and treat than facial acne, and it is more likely to leave dark marks or scars if it is deep or picked at.
Some bumps that look like acne are actually folliculitis, an inflammation of hair follicles that can be bacterial or fungal. Fungal folliculitis often appears as small, uniform, itchy bumps on the chest and back and does not respond to standard acne treatments. If your “acne” is itchy or not improving, ask your provider to evaluate it.
How to Prevent Acne on TRT
Simple daily habits often make a meaningful difference:
- Wash twice daily with a gentle cleanser, and after heavy sweating.
- Shower soon after workouts and change out of sweaty clothing.
- Choose non-comedogenic products, including moisturizer and sunscreen.
- Wear breathable fabrics and wash gym clothes, towels, and pillowcases regularly.
- Avoid picking or squeezing, which increases the risk of scarring and dark marks.
Over-the-Counter Treatments
Benzoyl peroxide body wash
Benzoyl peroxide reduces acne bacteria and helps clear pores. A benzoyl peroxide wash is a practical first step for back and chest acne: lather it on, leave it for a minute or two, then rinse. It can bleach towels and clothing, so use white towels and rinse thoroughly.
Salicylic acid
Salicylic acid exfoliates inside the pore and helps with blackheads and whiteheads. It is available in cleansers, sprays, and pads that are useful for hard-to-reach areas.
Adapalene
Adapalene 0.1% gel is a retinoid available without a prescription. It helps prevent clogged pores. Expect some dryness or irritation in the first few weeks, and use sunscreen during the day.
Prescription Acne Treatments
If over-the-counter care is not enough, your provider or a dermatologist may recommend prescription options.
Topical retinoids (tretinoin and others)
Tretinoin and related retinoids help keep pores clear and reduce new breakouts. They are usually applied at night because they can increase sun sensitivity. Acne may briefly seem worse during the first weeks before improving.
Topical antibiotics (clindamycin)
Topical clindamycin targets acne bacteria and inflammation in mild to moderate acne. It is usually combined with benzoyl peroxide to reduce the risk of antibiotic resistance.
Dapsone gel
Dapsone gel (Aczone) is FDA-approved for acne and can help with inflammatory lesions. Your provider will explain how and where to apply it.
Oral antibiotics
For moderate to severe or widespread acne, a short course of an oral antibiotic such as doxycycline or minocycline may be used, typically alongside topical treatment. Antibiotics are generally limited in duration to reduce resistance.
Isotretinoin (Accutane) and TRT
Isotretinoin, sold under names such as Absorica, Amnesteem, Claravis, and Zenatane and often still called Accutane, is reserved for severe, scarring, or treatment-resistant acne. Some men take isotretinoin while continuing TRT, which should be coordinated between the prescribing clinicians. Points to discuss:
- Isotretinoin requires enrollment in the FDA-mandated iPLEDGE program and regular monitoring.
- It can raise triglycerides and liver enzymes, so lab monitoring matters, especially alongside other medications.
- Common side effects include dry skin and lips, nosebleeds, and sun sensitivity. Report mood changes promptly.
What about spironolactone?
Spironolactone is sometimes used for hormonal acne in women. According to the American Academy of Dermatology, it is generally not prescribed to men for acne because of side effects such as breast tissue growth.
Adjusting Your TRT Plan
Because acne is driven by androgen exposure, your provider may review the TRT regimen itself, especially if acne is severe or persistent:
- Checking levels: labs timed to your dosing schedule can show whether testosterone is above target or peaking sharply.
- Dose or frequency changes: smaller, more frequent doses may reduce peaks. Some patients and clinicians also consider a different route, such as subcutaneous injections.
- Reviewing other contributors: other medications or supplements can also worsen acne.
Do not change your dose or schedule on your own. Work with your prescriber so symptom control and safety monitoring stay on track.
Supplements and Home Remedies
Evidence for supplements and home remedies is limited and mixed. A 2020 analysis found that zinc may help some people with acne, and topical tea tree oil has modest supporting data. Some people notice improvement with a lower-glycemic diet or less dairy. These approaches are not substitutes for proven treatment, and some, such as undiluted essential oils or apple cider vinegar, can irritate the skin. Check with your provider before adding supplements.
When to See Your Provider
Contact your provider or a dermatologist if you have:
- Deep, painful nodules or cysts
- Acne that is scarring or leaving dark marks
- No improvement after 8–12 weeks of consistent treatment
- Itchy, uniform bumps that may be folliculitis
- Acne affecting your confidence or quality of life
Frequently Asked Questions
Does acne from TRT go away?
For many men, acne improves after the first few months as hormone levels stabilize, especially with good skin care. Persistent acne often responds to treatment and, when appropriate, adjustments to the TRT plan.
What is the best body wash for back acne on TRT?
A benzoyl peroxide wash is a common first choice for back and chest acne. Salicylic acid washes are another option. If you suspect fungal folliculitis, ask your provider, since that needs a different approach.
Can I take Accutane while on TRT?
Some men do, under coordinated medical supervision with iPLEDGE enrollment and lab monitoring. Discuss timing and monitoring with both your TRT provider and the clinician prescribing isotretinoin.
Should I stop TRT because of acne?
Not on your own. Acne can usually be managed with skin treatment and, if needed, regimen adjustments. Talk with your provider before making any change.
