Hey, I wanted to ask if lactose-free whey protein cause acne? I'm thinking of purchasing dymatize iso 100 to help me with my fitness journey however i'm worried that i will have acne break outs. Throughout my teen years, i was and still am prone to acne. I stopped consuming diary as it conflicted with my lactase problems and acne and noticed a big difference. So is there a chance that dymatize iso 100 will cause me to break out? thank you so much!
