Does Creatine Cause Acne? What the Evidence Actually Says
Creatine has not been shown to cause acne in good-quality research, and most people who take it see no change in their skin. Breakouts that start with a new gym routine more often come from whey protein, sweat trapped under clothes, B-vitamin pre-workouts, or products contaminated with hormones. Testing one change at a time can reveal your trigger.
The worry is understandable. You start creatine, you start lifting, and a few weeks later your chest and back break out. Creatine then gets the blame because it is the newest thing you are taking. In reality, several other things changed at the same time. Here is what the evidence does and does not say, how to find the real cause, and how to clear your skin without giving up your training.
Breaking out on your face and your back since you started training?
Our Face + Body Clear Duo pairs an Acne Relief Face Wash with an Acne Relief Body Wash, both made with 2% Salicylic Acid and Niacinamide, to help unclog pores from jaw to shoulders.

No well-designed study has found that creatine causes acne, although few studies have looked at the question directly. Creatine has been studied extensively for safety and muscle performance, and acne does not stand out as a recognised side effect in that research. The absence of evidence is not absolute proof, so an individual reaction can't be ruled out completely.
Where did the DHT theory come from?
The theory comes from one small study, published in 2009, of college rugby players. Levels of dihydrotestosterone (DHT), a hormone linked to oil production, rose during a creatine loading phase. That finding is often repeated online as proof that creatine causes acne, but it has important limits:
- The study was small and has not been clearly confirmed by later work.
- It measured hormone levels in blood, not acne.
- Later studies have generally not shown meaningful changes in testosterone with creatine use.
So the link remains a theory rather than an established effect. Anyone especially prone to hormonal acne may still prefer to skip loading and take a steady daily dose, since that is the phase the study examined.
What else could be causing your gym breakouts?
Starting creatine usually coincides with other changes, and several have a stronger link to breakouts.
| Possible trigger | Why it may matter | What to try |
|---|---|---|
| Whey protein | The dairy-based acne link is stronger than for creatine | Try a plant-based protein for 6 to 8 weeks |
| Pre-workouts and B-vitamins | High doses of vitamin B12 are linked to acne-like eruptions | Check the label and pause them |
| Mass gainers and extra sugar | High-glycaemic diets are associated with more acne | Cut back on sugary shakes |
| Sweat and tight gym clothes | Friction and trapped sweat can inflame follicles | Shower and change soon after training |
| Testosterone boosters or contaminated supplements | Added or undeclared hormones can trigger severe acne | Stop, and speak to a doctor |
| Helmets, straps and shared equipment | Pressure and rubbing cause acne mechanica | Clean gear and add a barrier layer |
Sudden, severe acne across the chest and back in someone who trains hard is a particular reason to look closely at their supplement list. It is not typical of creatine, but it can occur with anabolic steroid use.
How can you tell if creatine is the problem?
Run a simple elimination test, because changing everything at once tells you nothing. Keep your training and skincare steady during the test.
- Write down everything you take. Include brand names and doses of creatine, protein, pre-workouts and any vitamins.
- Remove the most likely trigger first. That is usually whey or a pre-workout, not creatine.
- Wait six to eight weeks. Pimples can take weeks to develop, so a few days will not give you an answer.
- Remove creatine only if nothing changes. If your skin clears and flares again when you restart, you may have your answer.
- Take photos in the same light. Memory is unreliable when you are judging gradual change.
How should you take creatine if you are acne-prone?
A plain, steady dose is the sensible option. There is no evidence that it prevents acne, but it does keep things simple.
- Skip the loading phase. A steady 3 to 5 g a day reaches the same muscle levels, only more gradually.
- Choose plain creatine monohydrate. Avoid proprietary blends that add stimulants, vitamins or herbal testosterone claims.
- Buy from reputable brands. Look for third-party testing where possible, since supplement quality varies.
- Drink water as you normally would. Dehydration is not an established cause of acne, but staying hydrated supports training.
If you have kidney disease, take regular medication, or are under 18, check with a doctor before you start.
What is the best routine for gym breakouts?
Good post-workout hygiene and a salicylic acid cleanser cover most gym acne on both face and body.
- Wash soon after training. See our guide to sweat and workout breakouts for why timing helps.
- Use a salicylic acid wash. It helps clear oil and dead skin inside pores. For the back and chest, read how often to use a salicylic acid body wash, and leave it on for a minute before rinsing.
- Wear clean clothes every session. Choose breathable fabrics, and wash gym towels often.
- Use a light moisturiser and sunscreen. Oily skin still needs both, especially on outdoor runs.
- Avoid the temptation to scrub. Friction makes inflamed skin worse.
When should you see a dermatologist?
See a dermatologist if you have painful, deep or scarring acne, if it spreads quickly across your chest and back, or if it has not improved after 8 to 12 weeks of consistent care. Be open about everything you take, including any hormone or steroid products, because this directly affects treatment.
Frequently asked questions
Does creatine cause back acne?
There is no good evidence that it does. Back acne in people who train more often comes from sweat, friction, tight clothing, whey protein or hormone-containing supplements. Check those first before you give up creatine.
Will my acne go away if I stop taking creatine?
If creatine was not the cause, stopping it will make no difference. Allow six to eight weeks after changing one thing at a time, since pimples can take weeks to form and clear.
Does creatine increase testosterone or DHT?
One small 2009 study reported a rise in DHT during loading, but later research has generally not shown meaningful hormone changes. It also did not measure acne, so it does not prove that creatine causes breakouts.
Is whey or creatine worse for acne?
Whey has the stronger link with acne, probably through dairy proteins and their effect on hormones such as insulin. Evidence for creatine is much weaker, so whey is usually the better first thing to test.
Can I take creatine while using acne treatments?
Topical products such as salicylic acid have no known interaction with creatine. If you take isotretinoin or other prescription medicines, ask your doctor before adding any supplement to your routine.
