Does creatine cause acne?

What the evidence shows about creatine and acne

Acne has multiple drivers including hormones, sebum production, bacterial colonisation and inflammation. Creatine does not match documented acne mechanisms directly. Here is the honest picture.

1. The 2009 DHT study and what it actually showed

Van der Merwe and colleagues tested 20 college-aged male rugby players. The intervention group took 25 g creatine daily for 7 days then 5 g for 14 days. DHT (dihydrotestosterone) increased by 56 percent during loading and remained 40 percent above baseline at maintenance. The placebo group showed no change. The study did not measure acne or hair loss directly. It only measured the hormone.

2. Subsequent studies have not consistently replicated the DHT finding

Follow-up trials have not reliably shown the same DHT increase. The 2009 finding may have been an anomaly of small sample size or specific population. Larger reviews of creatine safety do not list significant androgen effects. The DHT story is widely repeated in popular discussion but rests on a single small study without robust replication.

3. Direct acne evidence is absent

No trial has measured acne outcomes with creatine supplementation as a primary endpoint. Anecdotal reports exist but anecdote is not evidence. Adults experiencing acne after starting creatine may have other concurrent changes (different diet, stress, sleep, skincare products, hormonal cycles) that are the actual cause. Self-blaming the supplement without controlled comparison is unreliable.

4. The mechanism would be hormonal not direct

If creatine were to cause acne the proposed mechanism is through DHT elevation increasing sebum production in androgen-sensitive sebaceous glands. This would only affect adults genetically susceptible to androgenic acne. Most adults do not show this sensitivity. Even if creatine modestly increases DHT in some users (which is not robustly established) the clinical acne effect would be limited.

5. Individual variation matters

Some individuals report new or worsened acne after starting creatine. These reports are real even if controlled evidence is absent. A 4 week stop and reassessment determines whether the supplement is the cause for you specifically. If acne clearly worsens on creatine and improves off it, you may be one of the responders. Most users see no skin changes.

How to identify if creatine is causing your acne in five steps

Use this framework rather than assuming the supplement is the cause based on coincidental timing.

Step 1. Photograph baseline skin before starting creatine

Consistent lighting (natural daylight, same angle, distance, exposure). Front face and any affected areas. No filters. Without baseline photos you cannot honestly evaluate any skin changes during supplementation.

Step 2. Identify other potential causes

Diet changes (more dairy, more processed food, more sugar). Stress and sleep changes. New skincare products. Hormonal cycles. New medications. Training intensity changes. These factors drive most adult acne changes far more than supplementation. Be honest about what else has changed.

Step 3. Continue your normal skincare routine

Daily gentle cleansing. Moisturiser. Sunscreen. Any prescribed acne treatments. Do not change skincare while testing whether creatine is the cause. The variable being tested is the supplement not other factors.

Step 4. Stop creatine for 4 weeks if you suspect a link

Creatine washout is 4 to 6 weeks back to baseline. Skin takes 4 to 6 weeks to clear if a trigger is removed. Stop the supplement entirely for 4 weeks. Compare current skin against baseline photographs. Clear improvement off the supplement: creatine may be a contributing factor for you. No change off: the supplement is not the cause.

Step 5. Make an informed decision

If skin clears off creatine and you want to use creatine for training benefits, consider whether the trade-off is acceptable. Some adults accept modest skin changes for performance gains. Others prefer to skip creatine to maintain skin clarity. Discuss with your dermatologist if uncertain. The choice is personal.

When creatine is a problem

Most users tolerate creatine without skin issues. Stop and see your GP or dermatologist if any of the following apply.

• Severe cystic acne developing or worsening on supplementation. Dermatology referral needed regardless of supplement use.
• Widespread rash rather than typical acne. Could indicate ingredient reaction.
• Acne with other symptoms (hormonal changes, fatigue, weight changes). Could indicate underlying condition.
• No improvement 4 weeks after stopping creatine. Likely not the cause. Investigate other factors.
• Persistent acne unresponsive to supplementation changes. See dermatologist for proper treatment.

Persistent or severe acne deserves dermatological assessment regardless of supplement use. Topical retinoids, benzoyl peroxide and prescription treatments have strong evidence for acne treatment. Supplement experiments should not delay proper acne management. NHS dermatology referral is available through your GP for serious or persistent acne.
