Accutane
"I am 19 years old with severe acne. I took this when I was around 16 or 17 for about 3 months. I was never happier with how my face looked I had absolutely not one pimple after taking this for 3 months BUT I stopped taking it because I was happy with the results when I was supposed to take it for 9 months. Don't do that! Because my acne came back almost just as bad. I hear if you take it for the full amount it works though. I honestly had no real side effects. I think because I only took it for 3 months."
