I feel for you-I have the same problem. My skin has been haywire since I was 14. I went back and forth to the dermatlogist for years, and they would prescribe an antibiotic, and my skin would clear up, I would go off the anti, and I would break out.
Finnally, I worried about developing antibiotic resistance, and as a last resort, tried Proactive. Not to try to sell you something, but the stuff works great.It took about 4 months to clear up initially, but it keeps my skin clear without drying or flaking. The cleanser is exfoliating, so over time, it has even lightened some acne scars.It's kinda expensive, but I consider it a neccesary expense.I know how hard it is physcologically to have bad skin, some people just don't realize, so I wish you the best of luck and hope you find something that works for you!
