Plastic surgery, being used to enhance or improve a person's natural appearance, is of course superficial. Whether to alleviate feelings of inferiority over breast size or to cover up burns from a fire, the aim is to improve how one looks and make them more attractive or acceptable to society in general. There are often situations where the surgery provides people with benefits beyond the surface, but it is even then still superficial (just not merely superficial).
I thinks it's superficial. People are trying to cover up who they are how they are born. It starts with braces for your teeth and ends with full face operations (cheeks, hair, wrinkles). But why ? Mostly because modern medicine used the techniques that were implemented for life saving surgeries for plastic surgery and evolved those techniques. Then some rich people who could afford it, did the surgery, the first braces etc. More and more people where doing it and now it's not a question of do you want to change something on your body, but, why don't you change something on your body, he, she ... Whoever did it too.
So now everybody feels peer pressured, until hopefully a new generation calls out the bullshit, and remembers what's important in life. Education, family, friends, relationships. And believe me you can live a decent life without plastic surgery, braces etc. The generation who influenced the world that we are now in did it too. The greatest minds that pushed borders did not need this superficial crap. It's all psychological. It's about accepting yourself. And in our generation as opposed to the old generation it just gets harder to accept yourself. Because there are now ways to always change the tiniest bits. In the end it won't make you happier and you will still be you. Focus on yourself on your strengths and cut yourself some slack. Accept yourself. We are all just humans.
And fuck those plastic surgeons doing all the cosmetic surgeries. They play with the patients insecurities that we all have. All humans have them. They take adavantage of this human psychological trait.
Just a note: I mean plastic surgery in the sense of cosmetic surgery/cosmetic medicine; not in the sense of reconstructive surgery (after accidents etc.)
Although some people may like plastic surgery because they believe it makes them look better or prettier, it still doesn't make it right. Plastic surgery is superficial and fake, even if it gives people confidence. They should be happy and content with what they look like and feel confident about what they look like. If they use plastic surgery to hide their flaws, it isn't what they look like originally and it is superficial and fake.
In some cases, yes, plastic curgery can be simple vanity and show a superficial personality. In many cases, however, it can bring back a sense of worth, can correct an accident, or take away a serious flaw that is noticeable and preventative for employment. Humans are judgemental by nature, and attractive people have certain doors open more easily and wider for them. getting rid facial deformities, bad teeth, or similar disfiguremnts can level a playing field.
