Protein supplements can cause pimples. Stop your protein supplements and they will disappear. Food causing pimples are high protein food (non vegetarian diet with lot of meat), milk and milk products except curd, fried food and sweets. Follow up with your dermatologist and ask if they can give you some other medicines as you are not responding to treatment. Discuss about procedures like peels or IPL. Warm regards.
