Depending on how bad it is, I would go to a private derm.
I have had acne for 7 years. 1 year mild-moderate then extremely severe for 4, now the past 2 years its been severe-moderate. i really didnt want to do Accutane, but after I realized its not going away, I decided to go for it..
I stopped all treatments for 1 month and went to a derm. They put me on Accutane. I'm 5 weeks in and its doing wonders. My skin looks much, much better but still really damaged (I don't got a lot of scars, but rather large pores all over). My only side effects are extremely dry eyes, which I already had, but Accutane made it a lot worse. I'm gonna manage that though.. If the acne returns I'm going on holidays (2 weeks) every 3. months to keep my acne at check, as this has worked before (in the sun all day and in and out of chlorinated water). 6 months after Accutane, I will be looking at laser treatments.
Anyway, I'm just saying there is still much hope.
