me men experience acne after starting testosterone replacement therapy (TRT). This is more common in younger men and those prone to oily skin or blocked pores.
Acne can appear on the face, back, chest, or shoulders, and is typically mild to moderate. It usually settles down once hormone levels stabilise, but there are steps you can take to reduce or prevent it.
At Hormn, we reduce the chance of acne by:
Starting at a low dose
Using stable, small, frequent injections
Adjusting dose based on bloodwork to maintain optimal but not excessive testosterone levels
Why Acne Can Happen on TRT
Testosterone increases sebum (oil) production. This can:
Block pores
Promote bacterial growth
Lead to inflammation and breakouts
Sebum production usually stabilises after a few months of consistent treatment.
What You Can Do
Here are practical steps that may reduce acne severity:
1. Diet
Lower dairy intake—especially cow’s milk, which may worsen breakouts
Reduce sugar and highly processed carbs
Avoid fried and high-oil foods
Limit chocolate, particularly milk chocolate
Stay well-hydrated
2. Lifestyle
Shower after sweating (gym, sauna, hot weather)
Wear clean, breathable cotton clothing
Avoid synthetic fabrics like polyester and nylon
Change pillowcases and towels twice a week
Don’t smoke—it reduces skin healing and worsens breakouts
Use non-comedogenic skincare products and avoid heavy oils on skin
3. Supplementation
Vitamin B5 (Pantothenic Acid) in high doses (e.g. 2000mg, four times per day) has shown anecdotal benefit in reducing oil production. Use only with doctor approval.
Zinc and Omega-3 fatty acids may help support healthy skin.
Give It Time
Acne is usually temporary and improves as:
Hormone levels stabilise
The skin adjusts to new oil production
Lifestyle changes reduce pore clogging
