Minocycline
"Can't say enough good things about Minocycline. I suffered from moderate/severe acne on my face, chest and back all throughout high school and this medication was the only thing that helped me. It took about a month to start to see results but after about 3 months I had absolutely no acne ANYWHERE. (Of course I made sure to have a good washing/topical regimen too) Just make sure you take this with no dairy products (they cause antibiotics to not work as well)and drink a lot of water . Minocycline is a live saver"
