I am 11 & have the absolute worst skin ever.?

okay, I am only 11 & my skin is TERRIBLE! I have had rocacea since I was 8, (I know its unusual) and I am SICK and TIRED of it! My skin is REALLY sensitive, and I do NOT want home remedies, because it just makes my skin even worse! Somebody told me I was too young to go to a dermatologsit, but I really think I need to.

But first, I want to try something called Exposed Skin Care ( heres the link http://www.exposedskincare0o0com/ )
I was wondering if exposed would be to harsh on my skin. I just really want clear skin.
