Hi, I am 29 years. Suffering from pimples and blackheads since many years. I have been to many skin specialist, dermatologists, cosmetologist. None of their medicines snd creams worked on me. The only medicine worked me was isotroin and minocycline tablets. While using this I have very good skin and no pimples. When I stop taking it, pimples come backs. But both the medicines are harmful. Particularly isotroin. Is there any medicine which will work like above medicines with any side effects?
