While there has been some decent advice here, I suggest hitting up
Acne.org and checking out their forums. Tons and tons and tons of information and personal accounts of everything from Accutane to Benzoyl Peroxide to holistic remedies.
As for 'Tane, I have three close friends who went on it, and all experienced some straaaange ass side effects. One, my first year roomate in college, had burning skin whenever he sweat for two years after the stuff. One had chapped lips so bad he couldn't speak a lot of the time because it would split them open. The last one got it the worst. He now has almost permanent Tinnitus, a constant ringing in the inner ear, which is nasty stuff.
One thing is for sure though, they all cleared up 100%.
