That's the problem with beauty isn't permanent. It happens to everyone from Madonna, Dick Van Dyke and Lynn Neilson. This doesn't apply to everyone tho. Tom Cruise, Scarlett Johansson and Dewayne "The Rock" Johnson have manage to be exceptions to this rule although it's much easier for men to do. In general women aren't really allowed to age. Even if there looks aren't important. I remember when the election was happening and people were dunking on Kamara Harris for having wrinkles like she isn't a woman in her 60's.
There's also a non-financial cost to keeping up with beauty standards via plastic surgery. Madonna is a perfect example. As soon as someone gets a facelift the ageing-clock speeds up and repeated lifts have diminishing returns until a person is left with an unexpressive piece of pleather for a face. Michael Jackson's nose was also a good example of such issues.
