How can i get rid of acne & backacne?

try this knockoff proactive that you can find at walgreens. it's called Skin Essentials, and it's exactly the same as proactive (only it's $12! cha channgg!) use all the steps on your back (and make sure you don't wear green, blue, or purple, because it will bleach it) and hopefully that will do the trick. Or just get a wash with benzoyl peroxide that you can use with a sponge or a loofa to lather up on ur back.
