I have the whitest of white skin, too, and it does show every little thing. I look at the sun
from inside and get freckles. If you decide to do anything, ONLY do it under the care of a certified/licensed dermatologist. Don't do it yourself, and don't buy some kit at the store.
But really, you have a nice face. Teen years are full of hormone changes that do awful things to our skin. See a dermatologist if you must, but I suspect you think it's really bad when it really isn't.
