How to see a Dermatologist?

Hi, i'm 15 and i'm a Little but spotty but not that noticeable, they cover up with make up, but i've recently noticed that i'm getting some on my chest, back and shoulders. I'm also paranoid that i have soft, light colored hair on my stomach that i'm paranoid about, even though it's not that noticeable. I don't want to wear a swimsuit and going on holiday in the summer if i'm turning into a disgustinty hairy freak. Does any other girls have this problem?
