I've thought of doing something, since my face has lots of old scars and pock marks from when I was younger and had bad acne. (I later found that the acne meds were making it worse, and dairy products make me flair up... some kind of reaction or something. Once I got non-acne soap that was gentle for sensitive skin and cut out dairy, my face cleared.)
But, anyway, the peel thing sounds interesting and so does the dermabraision thing.
