I Have Tried Almost Every Acne Medication Available, Including Accutane.

I have tried almost every acne medication available, including Accutane. I've done accutane once when I was young, which cleared up my acne almost completely. About a year later, my acne came back. I waited a few years to see if it would clear up with age, but I'm 24 now and still have acne - and it's getting worse as time goes on. I started accutane a second time last year, but I only made it through 2 months of accutane treatment before I was international for a while and unable to re-fulfill my prescription.

Is there anything else I can try? Any non-prescription medicine or alternative methods? Or can I try going on Accutane a 3rd time as I was unable to complete the course the second time?
