I'm going on a long holiday in 4 weeks but I'm really self-conscious of my back acne. I have tried so many things, taking dairy out of my diet, taking sugar out of my diet, using creams with benzoyl peroxide. I even went on a pill prescribed by my GP but I had a terrible reaction to it, breaking out in hives. Some things that I've tried had short-term effects but nothing seems to last! Please help I really don't know what to do
