Personally I use wintergreen rubbing alcohol on the acne. If it is on your back pour some on a back brush in the shower and scrub you back with it. It it is on your face pour some on a wash cloth and wash your face with it. It will dissolve the oil that the bacteria are feeding on and it will kill the bacteria. The red zits will go away. I have told this to a number of people and it has worked for them all. It's cheap and doesn't harm you liver like accutane.
