Average Age
According to statistics compiled by the American Academy of Cosmetic Surgery, the average age of a person who has undergone a cosmetic surgical procedure is 42 years old. This is for either invasive procedures, like liposuction and blepharoplasty, or non-invasive procedures, like laser hair removal and microdermabrasion.
Apparently, within the last few years, this age has increased. It was 40 before.
