Minocycline
"I have been dealing with acne for a little over a year now. When I was 19 I randomly started to break out worse than I ever had my whole life. I think it was a combination of changing hormones and stress that caused it. Bottom line: I was desperate to return to the normal complexion I had growing up. I tried many different ways of treating it, but when I went on minocycline my face cleared up within 3 days. Yes, it had gotten slightly better with the birth control, so I don't know how well this will treat severe acne, but it definitely treated my close-to-severe acne. Your acne might need to be treated on the inside as well as the outside."
