Please consider bowel and liver cleansing. All the information is free and on Curezone site. You must address the deep-rooted source of the problem...which is a body full of toxic crap from poor diet and medications taken.
I have cured my adult onset Acne completely from cleansing alone. Nothing else can. Start the bowel cleansing and doing enemas at home (yes, enemas) and you'll see a difference in a few weeks. I promise.
