Prednisone can cause acne during prolonged use. Current evidence describes prednisone acne as steroid acne, an acne-like breakout tied to high corticosteroid levels. DermNet defines steroid acne as an acne-like eruption with high circulating corticosteroids, from Cushing disease or systemic steroid treatment. It separates this condition from steroid rosacea from long-term topical use, as described in the DermNet guide to steroid acne.

How does it look different from regular acne?
Prednisone-related lesions tend to look uniform. They appear as small red inflammatory papules, which are small solid bumps, and pustules, which hold visible pus.
Most people develop few or no comedones, which are blackheads and whiteheads. Breakouts favor the chest, upper back, and face. That monomorphic pattern, where spots look alike, contrasts with acne vulgaris, where blackheads, whiteheads, bumps, and cysts mix together.
- Prednisone acne: many small, similar red bumps with pus, few blackheads
- Acne vulgaris: mixed blackheads, whiteheads, larger inflamed spots, and uneven sizes
When does it start and who gets it?
The eruption usually begins within days to a few weeks of starting steroids. Risk and severity rise with higher dose, longer use, and personal acne susceptibility, according to the RACGP review of stubborn pimples.
Anyone taking systemic corticosteroids can develop it. Cases became more widely reported as corticosteroid use grew after organ-transplant and chemotherapy protocols.
What drives the breakout?
The exact process remains incompletely understood. Researchers point to several possible contributors in hair follicles and oil glands.
Proposed factors include Propionibacterium acnes bacteria, TLR2 immune signaling, oil-gland susceptibility, and extra Malassezia yeast growth. No single factor explains every case, so treatment focuses on calming lesions rather than fixing one cause.
What helps skin recover?
Steroid acne usually improves within weeks after stopping the responsible steroid. Doctors manage it by stopping the drug where medically possible plus standard acne care such as benzoyl peroxide.
The FDA label carried by the U.S. National Library of Medicine DailyMed lists acne among dermatologic reactions to prolonged prednisone, alongside striae, thinning skin, hirsutism, and increased sweating, in the FDA label for prednisone.
- Keep the prescribing clinician informed about new breakouts
- Ask about dose, duration, and safer acne-care options
- Do not stop or taper prednisone without clinician guidance
