Creatine and Acne: Does This Supplement Trigger Breakouts?

Creatine is one of the most researched and widely used sports supplements in the world. But a significant number of users report increased breakouts after starting creatine — often within weeks of beginning supplementation. Is there a real mechanism, or is it coincidence?

The DHT Hypothesis

The most discussed proposed mechanism involves dihydrotestosterone (DHT). A 2009 study published in Clinical Journal of Sport Medicine found that creatine supplementation in rugby players significantly elevated DHT levels relative to testosterone — a ratio shift that persisted over the three-week study period.

DHT is a potent androgen that directly stimulates sebaceous glands to produce more sebum and accelerates skin cell proliferation in hair follicles. Both mechanisms promote acne formation. DHT sensitivity of the sebaceous gland varies between individuals, which would explain why some creatine users develop acne while others see no skin change at all.

Why the Evidence Is Not Definitive

The 2009 study was small (20 participants) and has not been replicated definitively. Creatine does not contain androgens and is not directly anabolic in the hormonal sense. Some researchers argue the DHT effect is modest and unlikely to be clinically relevant for skin in most people.

It is also worth noting that creatine supplementation typically accompanies increased exercise intensity, increased caloric intake, potential protein supplement use, and disrupted sleep during hard training phases — all of which can independently affect acne. Separating the creatine effect from the surrounding training context is genuinely difficult.

The Whey Protein Confound

Many people who start taking creatine also start or increase whey protein at the same time. Whey is one of the most well-documented acne triggers through IGF-1 and insulin signalling. If you broke out after starting creatine plus whey together, creatine may not be the primary driver.

How to Test Creatine's Effect on Your Skin

Stabilize your diet (remove or keep constant protein supplements and other variables)
Stop creatine for 4 weeks and track your skin carefully
Reintroduce creatine while keeping everything else constant
Track skin for 3-4 weeks — both improvement on removal and return on reintroduction

This structured approach gives you actual data rather than a guess. Many people who blame creatine find that whey protein or diet changes made simultaneously were the real trigger.
