"accutane is an isotretinoin- the most powerful medicine for fighting acne. it has a 90% success rate. during a period of months (usually 4 to 5), you take a pill every day. the vitamin c gets rid of the small openings where testosterone goes through. this is a permanent change. usually those openings, which arrive from ages 10-15, and go away around ages 21-26, are rid of with accutane. that means that the testosterone cannot get through, and cannot produce acne anymore. during the treatment, 99% of the patients will experience dryness of the skin, eyes, and lips. for the majority of people, it is a worthwhile treatment."
