I believe the blotched surgeries are as high as 35%. I was only 27 when I went into an eye doctor (medical doctor) and he blotched it really bad. He used me as an experiment which I recently realize....
70% of women and men regret having plastic surgery because they said that is ruined their faces or bodies and that they wished they'd never had it because they looked better before the surgery
The best thing I can tell you is, check the doctor, make sure his degrees are legit.
Make him answer any question you have.
Ask for pictures of his past procedures. Lots of cosmetic surgeons ask...
