Have you taken any antibiotics at all? A severe case like that won't be cured by any soap or shampoo I'm afraid. Cystic acne is too deep into the skin to be affected by anything you put onto the skin. As some already pointed out; watch for supplements as you may have intolarance to something. I assume you do protein shakes and that sort. As for accutane.. I did it and never regreted it either. It didn't stop me from going to the gym or like that. Good luck!
