SkinTastic,
I'm also 19 and terrifed of getting older but for different reasons. I think figuring yourself out, ultimately being genuinely as happy as you can someday, and living with the smallest amount of worry is more important than what your skin looks like. In no way am I trying to make your fear sound illegitimate, but try to think of it from that perspective. And hey, there's always plastic surgery if you believe in it. Take care
