As I understand, the bulk of cosmetic surgery is for real problems like a clep palate, covering a severe burn, or removing abnormalities like tags, warts and other growths.
When I was a kid, my right eye would only open half way. My parents put me through cosmetic surgery so the eye open all the way.
While I dislike cases where healthy people get nose jobs and face lifts, I suspect that the bulk of the industry is doing good things for people who have serious problems.
