Key Takeaways
- Testosterone Replacement Therapy (TRT) can be associated with acne in some men, although not everyone receiving TRT will develop breakouts.
- Androgens, including testosterone and dihydrotestosterone (DHT), can increase activity in the skin’s sebaceous glands and contribute to greater oil production in people who are susceptible to acne.
- The relationship between TRT delivery method and acne is individual. Injections, gels and creams produce different hormone exposure patterns, but treatment should not be changed solely to manage acne without advice from the prescribing practitioner.
- Skin type, previous acne, genetics, sweat, friction, diet and other health or lifestyle factors can also influence breakouts while someone is receiving TRT.
- TRT Australia provides an Australia-wide telehealth and administrative pathway with ongoing bloodwork and clinical review where appropriate, while independent registered medical practitioners make all treatment and prescribing decisions.
Can Testosterone Treatment Cause Acne?
Yes, acne can occur during testosterone treatment. Androgens such as testosterone and DHT influence sebaceous glands, which can increase sebum production and contribute to blocked pores and inflammatory acne in susceptible people.
Not everyone on TRT develops acne, and there is no single timeline that applies to every patient. Breakouts can be influenced by genetics, previous acne, skin type, hormone exposure, sweat, friction, skincare and other individual factors. If acne appears or worsens while you are receiving TRT, it should be discussed with the practitioner managing your treatment rather than treated as a reason to change your dose or protocol on your own.
At TRT Australia, bloodwork and relevant health information form part of the assessment and ongoing care pathway. Independent registered medical practitioners make all clinical and prescribing decisions, including whether any change to treatment is appropriate when side effects or other concerns develop.

How Can Testosterone Trigger Acne at the Skin Level?
Acne develops within the pilosebaceous unit, which includes the hair follicle and sebaceous gland. Increased sebum, abnormal shedding of skin cells, Cutibacterium acnes and inflammation can all contribute to the development of acne.
TRT does not create a completely different form of acne. Instead, androgen exposure can influence processes that already play a role in acne, particularly sebaceous gland activity and sebum production.
Acne is influenced by several factors, including sebum production, blocked follicles, skin bacteria and inflammation.
The DHT-Sebum Connection
Dihydrotestosterone (DHT) is an androgen that can act on androgen receptors within the skin. Androgens can stimulate sebaceous gland activity and increase sebum production, which is one reason acne can become more noticeable in some people during testosterone treatment.
The relationship is not determined by a blood testosterone number alone. Individual sensitivity of the skin and sebaceous glands also matters, which helps explain why two people with similar hormone results can have very different skin responses. Relevant bloodwork can form part of overall treatment monitoring, but acne itself still needs to be assessed clinically.
Excess Sebum and Clogged Pores
Sebum is a normal part of healthy skin, but excess oil can combine with dead skin cells and contribute to blocked follicles. Cutibacterium acnes can then participate in the inflammatory process that produces papules, pustules and other acne lesions.
If oil production increases after starting testosterone treatment, someone who is already prone to acne may notice more frequent breakouts. The timing and severity vary substantially between individuals.
Inflammation Also Plays a Role
Acne is an inflammatory skin condition as well as a disorder involving sebum and blocked follicles. Androgen signalling can influence several processes within the pilosebaceous unit, but deep or cystic acne should not automatically be assumed to be caused only by TRT.
Painful, scarring or persistent acne should be assessed by an appropriate healthcare practitioner because specific acne treatment or dermatology input may be required.
TRT, Acne and Hormone Exposure
TRT Delivery Method and Acne
A common question is whether TRT injections cause more acne than gels or creams. Different administration methods can produce different patterns of testosterone exposure, and individual skin responses can vary with the treatment plan.
However, there is no universal rule that one TRT method will prevent acne for every person. The most appropriate treatment method should be selected for clinical reasons by the prescribing practitioner, not chosen solely on the basis of an online comparison of acne risk.
If acne appears while you are receiving TRT, discuss it with your prescribing practitioner. They can consider the timing of the skin changes alongside your blood results, overall treatment response and other relevant factors before deciding whether any change is appropriate.
Different TRT administration methods can produce different hormone exposure patterns, but the appropriate treatment method is an individual clinical decision.
Personal Factors That Influence TRT-Related Acne
Not every man on TRT will develop acne. Genetics, previous acne, skin type and individual androgen sensitivity can all influence whether breakouts occur.
A history of significant adolescent or adult acne may indicate that the skin is more responsive to androgen-related changes, although it does not mean acne will definitely return during TRT.
Men with naturally oily skin may also notice changes more readily because their sebaceous glands already produce a higher baseline amount of oil.
Age may also affect skin characteristics, but it should not be used to predict with certainty who will or will not develop acne during testosterone treatment.
Lifestyle Factors That Can Influence Breakouts
Diet can be relevant to acne in some people. Research has linked higher-glycaemic dietary patterns with acne severity in certain populations, although diet is only one of many contributing factors and should not be treated as the sole cause of TRT-related breakouts.
Sleep, stress and general health may also influence inflammatory skin conditions. Improving sleep and managing stress can support overall health, but persistent acne still deserves proper clinical assessment rather than relying only on lifestyle changes.
Exercise itself is not inherently a cause of acne, but sweat, friction and occlusive clothing can contribute to body breakouts. Showering after training, changing out of sweaty clothing and using non-comedogenic skin products may help reduce these triggers.
Managing Acne Concerns While on TRT
TRT Australia provides an administrative and telehealth pathway with access to independent registered medical practitioners and ongoing monitoring where appropriate.
Acne during TRT can range from mild oiliness or occasional breakouts to more persistent inflammatory acne. The appropriate response depends on severity, medical history, other skin conditions and the overall treatment plan.
Do not stop, increase, reduce or otherwise change prescribed TRT solely because acne develops without first discussing it with the treating practitioner. Mild acne may be managed with general skincare measures, while persistent, painful or scarring acne may require specific medical treatment or dermatology review.
At TRT Australia, the service pathway begins with a free initial consultation explaining the process, bloodwork requirements, service pricing and next steps. If you progress, an independent registered medical practitioner conducts the medical assessment and remains responsible for treatment and prescribing decisions. Book a free initial consultation to understand how the assessment pathway works.
Frequently Asked Questions (FAQs)
Does everyone who takes TRT get acne?
No. Acne is a possible skin effect of testosterone treatment, but many people receiving TRT do not develop significant breakouts. Individual androgen sensitivity, previous acne, skin type, treatment factors and other contributors can all influence risk.
How long does TRT acne last?
There is no universal timeframe. Acne may appear after testosterone treatment begins or after other treatment changes, but the duration and severity vary between individuals. Some cases settle, while others persist and require specific acne treatment. Persistent or worsening acne should be discussed with your healthcare practitioner.
Which TRT method is least likely to cause acne?
There is no administration method that guarantees someone will avoid acne. Injections, gels, creams and other approaches can produce different hormone exposure patterns, but the appropriate TRT method should be selected by the prescribing practitioner based on the individual’s clinical circumstances rather than acne risk alone.
Should I stop TRT if I develop acne?
Do not stop prescribed TRT solely because acne develops without discussing it with your treating practitioner. The appropriate response depends on the severity of the acne, the reason treatment was prescribed and your overall clinical circumstances. Your practitioner may recommend skincare measures, acne treatment, further assessment or another management approach.
