Adjust or Remove Whey Protein if It Causes Acne

If whey protein appears to cause or worsen acne or other skin symptoms, remove it for a couple of days or weeks and assess your response. For women who notice symptoms during particular menstrual-cycle phases, stop whey during those phases and use it only in other phases if tolerated. If acne is troublesome, remove whey altogether and replace it with casein protein or another high-quality protein, then see how you react.
