I was prescribed (ro)accutane a few years ago due to some quite bad acne on my shoulders/back, and it was pricy as hell. Also, it takes a few months to kick in, really, and the first month or so it tend to get alot worse. And prepare for some seriously dry lips. And you can't tan or anything for a long time after you've finished taking it. I advice you to try EVERYTHING else before you even consider it. Might sound harsh, but seriously, it's like the last resort.
