hi! do whiteheads always purge into pustules before subsequently going away? or do they go on their own without a purge of any form? currently doing the water only regimen and my oiliness has most definitely gone down whilst i still have mild acne on my forehead. three weeks in now. my diet is good, i drink plenty of water, etc etc.. god for weeks my face felt slightly irritated though now im quite sure it's drying down. Help? :^) x
