If people get some cosmetic assistance what's the problem? It's their body and face. I'm thinking of someone suffering from depression who's spent too many hours with a furrowed brow making them look permanently angry and wants to try Botox just to soften the lines a little. Is there anything wrong with wanting to look a bit fresher and happier?
Staying young and attractive certainly seems to be hugely important in today's society. It's difficult to imagine anyone bemoaning the fact that they're beautiful; being physically attractive is considered fortunate, and when beautiful people to complain about their beauty, it seems ungrateful almost.
