Isotretinoin
"I had mild to server acne at different times throughout years but then I finally decided to try Accutane. Initially, I did have an initial breakout which worsened the skin condition (more acne), which lasted for approximately 1.5months. But once the skin started getting better, everything started disappearing slowly and now I'm 4.5 months in and only have the red/brown marks left but all my acne is gone! The first few months will be harsh, and your self-esteem will probably get hit. But just go through the whole cycle - you won't regret it in the end."
