I can understand someone who has huge nose, or some really difficult facial problem having plastic surgery - and the dividing line between aesthetic and remedial plastic surgery can b e grey and fuzzy at times
Other than that I see plastic surgery as being self-mutilation. Look at Katie Price. her response to every setback in her life is - plastic surgery -, I have lost count of how many boob jobs she has had, plus all the rest. It is clear that her plastic surgery has nothing to do with quietly enhancing her looks but some visceral need for self -harm, with someone else doing the damage for you.
The same applies to that group of girls, and it is only a small group, who from a young age are having fillers and botox and other treatments. With all of them, the before is better than the after.
I am not saying that we shouldn't look after ourselves, titivate a bit, but physically changing your body strikes me as deeply unsettling.
