Isotretinoin
"If your face doesn't respond to over the counter products, you don't need to try everything out there.  ProActiv, SkinID, OXY, they are all the same!  Don't hesitate to try this miracle drug.  Pay attention to the side effects, of course, but this is not just a treatment, it is a cure.  I had severe acne from 16 - 20 and I tried everything!  Doctors were so reluctant to use this Accutane, keeping it as a last resort.  Once they were finally convinced I wasn't responding to anything else, and that I wouldn't just outgrow it, they finally put me on it, and the results were dramatic.  Within weeks, I could actually feel the change in my skin.  My skin finally felt normal, instead of greasy and painful.  I wasn't afraid to touch it anymore."
