Use a non-comedogenic cleanser with salicylic acid to unclog pores Stay hydrated: Creatine draws water into your muscles, so drink plenty of water throughout the day Wear breathable fabrics: Choose moisture-wicking, loose-fitting workout clothes that don't trap sweat against your skin Keep your hands off your face: Avoid touching your face during and after workouts Consider your protein source: If you're mixing creatine with whey protein, try switching to pea protein or another plant-based alternative that's less likely to trigger breakouts Stick to recommended doses: Take 3-5 grams daily for maintenance rather than prolonged high-dose loading phases Maintain a consistent skincare routine: Use oil-control products if you're prone to acne, and don't skip your regular cleansing routine When to See a Dermatologist If you experience persistent or severe breakouts after starting creatine or changing your workout routine, consult a dermatologist
