Creatine probably isn’t going to make you break out. There’s no direct evidence linking creatine supplementation to acne, and the International Society of Sports Nutrition lists weight gain as the only clinically significant side effect found in the research literature. That said, there’s one indirect hormonal pathway worth understanding, and a few practical reasons why people who start taking creatine sometimes notice more breakouts.
The DHT Connection
The main reason this question exists is a single 2009 study on college-aged rugby players in South Africa. After seven days of creatine loading (25 grams per day), participants’ levels of dihydrotestosterone (DHT) rose by 56%. DHT stayed about 40% above baseline even after two weeks on a lower maintenance dose. Testosterone itself didn’t change, meaning creatine appeared to speed up the conversion of testosterone into its more potent form.
DHT matters for skin because it’s one of the hormones that drives oil production in your sebaceous glands. More oil can mean more clogged pores, which can mean more acne. This is the same hormone implicated in hormonal acne along the jawline and in male-pattern hair loss. So on paper, a 56% bump in DHT sounds like a plausible acne trigger.
Here’s the problem: no other published study has replicated those DHT findings. The study involved only 20 participants, all young male rugby players already training at high intensity. And critically, the researchers never measured skin outcomes. They didn’t look at acne, oil production, or anything dermatological. The leap from “DHT went up in one small study” to “creatine causes breakouts” is a leap the science hasn’t actually made.
What the Broader Evidence Shows
A case-control study comparing supplement users with and without acne found no statistically significant association between creatine use and breakouts. The odds ratio was 1.81, but the result wasn’t significant (p = 0.448), meaning creatine users weren’t meaningfully more likely to have acne than non-users in that sample. Whey protein, on the other hand, showed a much clearer link to acne through its effect on insulin and a growth hormone called IGF-1. Dairy-based protein supplements spike insulin despite having a low glycemic index, and that insulin surge triggers a cascade of hormonal changes that promote breakouts.
If you’re taking creatine alongside whey protein shakes, the whey is a far more likely culprit for any new breakouts. The same goes for other dietary changes that often accompany a new supplement routine, like eating more calories, consuming more dairy, or increasing sugar intake around workouts.
Why Breakouts Happen When You Start Creatine
People who start creatine usually start training harder. That’s the whole point. And harder training comes with more sweat, more friction from gym clothes and equipment, and more time spent in warm, humid environments. All of these are well-established acne triggers that have nothing to do with the creatine itself.
Sweat doesn’t directly cause pimples, but it creates the conditions for them. Oil production increases with physical activity. Bacteria thrive in warm, moist skin. Tight workout clothes create friction along your chest, back, and waistline. When you combine all of that with the inflammation from intense exercise, you get the classic “gym acne” that people mistakenly attribute to whatever new supplement they started taking at the same time.
This is a textbook case of correlation, not causation. You changed multiple variables at once (new supplement, harder workouts, more sweat, possibly a new diet), and your skin reacted. Creatine gets the blame because it’s the most visible change.
Keeping Your Skin Clear While Supplementing
If you’re worried about breakouts while taking creatine, focus on the factors you can actually control. Shower as soon as possible after training. Sweat that sits on your skin mixes with oil and bacteria, giving pores more opportunity to clog. Use a mild, oil-free cleanser on your face and any areas prone to breakouts.
Wear clean workout clothes every session. This sounds obvious, but re-wearing a slightly damp shirt from yesterday is an easy way to introduce bacteria back onto your skin. If you use shared gym equipment, wipe it down before pressing your skin against it. Use oil-free sunscreen if you train outdoors.
Pay attention to the rest of your supplement stack too. If you’re mixing creatine into a whey protein shake, try switching to a plant-based protein for a few weeks and see if your skin improves. That simple swap can help you figure out whether dairy, not creatine, is the real trigger. Similarly, if your new training diet includes more processed carbs or sugary sports drinks, those insulin spikes could be contributing.
The Bottom Line on Creatine and Acne
No study has directly shown that creatine causes acne. One small study found elevated DHT levels, which could theoretically increase oil production, but that hormonal change has never been confirmed in follow-up research and was never connected to actual skin outcomes. The most comprehensive reviews of creatine’s safety profile don’t mention acne or breakouts as a side effect at all. If you’re breaking out after starting creatine, the training itself, your diet, or other supplements in your routine are more likely explanations.
