I used to have a lot of acne on my back and my chest. I get the ocassional one now (I'm 18) but for the most part they're gone. However, they've left my skin looking like that of a leopard's. Is there anything I can do to make the marks fade? I asked my uncle, and he's a doctor and he said, "They'll go away on their own eventually."....I don't wanna wait that long. Thank you everyone - any advice helps.
