Does creatine cause pimples (acne)?
No studies or reasonable scientific theory suggest creatine causes pimples or acne. Rumors to the contrary are undoubtedly related to the false perception that creatine is closely related to steroids. Steroids can cause acne, creatine can’t. Increasing the quality of and quantity of your diet as well as intense weight training can (will) increase the body’s hormone production (testosterone). As a main cause for acne breakouts in some is believed to be increased hormone production, the person beginning a mass gain program may experience acne breakouts. Whether or not the trainer was supplementing with creatine wouldn’t have a major effect one way or the other.
