Can Creatine Cause Acne? What the Research Does and Doesn't Show

The evidence doesn't support a direct link between creatine monohydrate and acne — no trial has measured skin outcomes in people taking creatine. What's documented is one step removed from the question: a small trial found creatine supplementation raised a hormone called dihydrotestosterone (DHT), which separate dermatology research links to acne. Nobody has connected those two dots with an actual creatine-and-skin trial.

What the evidence doesn't support

It doesn't support creatine causing acne directly — no trial has looked at acne, breakouts, or oily skin in people taking creatine. It doesn't support creatine being acne-free either; that specific outcome simply hasn't been studied. What follows is the closest available research, and it stops well short of an acne finding.

What the trials found

A double-blind, placebo-controlled crossover trial in 20 college-aged male rugby players measured testosterone and DHT before and after creatine supplementation: 25 g/day for 7 days (loading), then 5 g/day for 14 days (maintenance — the same maintenance dose as our own label). Total testosterone didn't change. DHT, a more biologically active form of testosterone, rose by 56% after the loading week and stayed about 40% above baseline through the maintenance period. The ratio of DHT to testosterone rose similarly. The study's own authors described the long-term clinical significance of that change as unclear and said it warranted further investigation — they did not claim it was harmful, and they did not measure any skin outcome.

Separately, dermatology research on sex hormones and acne describes acne as an androgen-driven skin condition: skin oil glands (sebocytes) can convert other hormones directly into DHT, and DHT acting on androgen receptors in those cells is tied to oil production and inflammation involved in acne. That's background mechanism from skin research generally — not a study of creatine, and not a measurement of DHT-and-acne together in the same people.

Put together: one small trial (20 rugby players, three weeks) shows creatine can raise DHT at a dose matching typical label directions. Separate dermatology literature shows DHT is a driver of acne in general. No study connects the two directly in creatine users specifically, so the honest answer is a plausible mechanism with a documented first step, not a demonstrated outcome.

Questions people ask

Can creatine cause acne?

No trial has tested that directly. What's documented is that creatine can raise DHT, a hormone separately linked to acne in dermatology research — a connected mechanism, not a demonstrated acne outcome.

Does creatine raise DHT?

One small trial (20 rugby players) found DHT rose 56% after a week of loading and stayed about 40% above baseline through two weeks of maintenance dosing. That's the extent of the research — one trial, one population, three weeks.

Does creatine cause hair loss too?

That question comes up for the same reason — DHT is separately linked to androgenic hair loss in other research. No trial has measured hair loss outcomes in people taking creatine either.

Should I stop creatine if I get acne?

That's a decision for a doctor or dermatologist, who can assess your skin and other causes. The research here doesn't establish that creatine caused it, or that stopping would resolve it.

When to talk to a doctor

Acne is a skin condition with several known causes and is diagnosed and treated by a doctor or dermatologist — creatine monohydrate is not a treatment for it, and the research here doesn't establish it as a cause either. If you develop new or worsening acne, or you already see a doctor for a skin condition, talk to a doctor or dermatologist about it directly.
