"can&#039;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"
