Dermabrasion is yet another tool in the modern plastic surgery arsenal, and it's less invasive than most. It involves sanding down rough skin until shiny new skin is revealed, in a process that's much less expensive or intensive than, say, a traditional face lift.
Plastic surgery isn't just for the vain; in fact, I was originally developed as a restorative treatment, intended to aid the disfigured. If you suffer from a deformity or disfigurement due to accident, surgery, or environmental damage, it may be your best bet for restoring your features -- and it will probably be covered under your insurance.
