The old "Twilight Zone" had a couple of episodes about plastic surgery.
One is the famous "In The Eyes Of The Beholder", with Donna Douglas (Ellie Mae of the "Beverly Hillbillies") which was updated and remade as an episode on "Night Gallery" in the early 1970's.
Then there is another one about an old couple who go to get rejuvenated, and then realize their assets will allow only one of them to undergo the procedure. They do each try it as I recall, and then decide in the end that they are fine the way the are and walk off together to spend their Golden Years together in peace and harmony.
There were others, one I recall mostly about a totalitarian State that required extreme conformity in which everyone had to be perfect and beautiful.
