Back hair and acne and prom?

since you have acne, the best thing you can do is start there. wash your back really good with acne wash. but it won't disappear over night. the easiest thing to do, is buy a cardigan. you can get super cute ones. i get my cardigans at target, pricey i know. but they are really durable and totally adorable. they come in tons of colors(: good luck and have fun
