I've never personally had a bad acne problem, but my two best friends both had quite bad acne in high school. To make the story short, they both went on accutane and they both have no acne problems now. The one friend stayed on it for maybe like 6 months, then quit and never had the problem again, where as the other cleared up and quit, then it came back. He used it again after that for about 6 months and has been free of acne since then. Anyways, I'm not saying you should use it, but I've seen it work for people, so it might be worth a shot.
i can pick at absolutely nothing on my face for like 10 minutes. then i actually end up having something there stupid. its so fun tho
