zinc supplementation? like zinc 30mg three times a day (with meals) in forms other than oxide or carbonate? It should reduce scarring if nothing else.
I'd say go for the Accutane man. Everyone I've seen on it had near Crystal C. skin. The side effects are overhyped IMO, just put on some chapstick and basically you have taken care of the most annoying side effect, and they monitor you while you are on it so no worries. If you are extremely worried about your liver just take milk thistle, but you don't have to.
