“(I) have recently stopped taking creatine because I believe it to be the reason my face has broken out in what the dermatologist calls a light form of acne – small red bumps and pimple like. This first started on my forehead and now is all over my face.”

“I noticed that after taking creatine for about a month, I broke out in acne heaps. I went to the dermatologist and he confirmed that it the creatine was probably raising the testosterone in my body. Too much hormones=acne.”

“I began taking creatine about two months ago. Friends began noticing a difference. However, I began to break out on my face. I discontinued using creatine for about two weeks. I just started again and sure enough, more break outs.”


“When I take creatine, I seem to get zits, is there a cause and effect relationship here, or just coincidence?”


Part 1: “I have broken out with pimples every time I have started using creatine. When I stop, they go away.”

Part 2: “I wouldn’t just break out with several pimples, I am talking pustules. Not pretty. And at 31, I should be well past that stage. I didn’t change anything else about my diet, exercise, or skin care regimen. That is why I am certain it was the creatine. I tried it a few different times just to make sure, too. ”
