[Star Trek] How are most people not looking like supermodels with all the advancement in cosmetic surgery?

You can get relatively non-invasive, pain free, cheap and risk free surgery to make you look like a whole other species. Think of how many people are unhappy with their looks. Their noses, foreheads, jaws, lips, breasts, whatever. Wouldn’t most people take advantage of this system and transform themselves into perfection, or at least, wouldn’t many people at least somewhat improve their looks through cosmetic surgeries? There should be many people walking around looking like supermodels. Good looking people like Uhura, Seven of Nine should be no longer an exceptional sight like nowadays but the norm.

How common is cosmetic surgery in Star Trek?

>Think of how many people are unhappy with their looks.

This is a common 20th/21st century viewpoint...   But in the 24th century, mankind has grown out of those attitudes .

For the most part, mankind has evolved out of those materialistic views.  Things such as personal wealth, fame, fortune, and with that one can assume **vanity** went along with those vices.  By the 23rd century, our society has evolved out of judging people and creating status levels based on those gains and achievements.   Sure there would still be a minor few that desire those accomplishments, but they would be far and few between.

We're also talking about the fact that MOST of the people we observe are aboard a Federation Starship... an otherwise "military" type vessel where those same non-materialistic points of view are more or less encouraged and promoted even more so.   That said, have a look around the Enterprise D, for example... most of those people ARE actually "attractive" by 21st Century standards.  Chalk that up to a more consistent and healthy way of living overall due to our society's evolution.  But as far as glitz and glamour, it just doesnt exist like you are thinking with your 21st century mindset.
