Koreans' acceptance of plastic surgery is really high. I think another reason is that many people have plastic surgery, and everyone can accept it, so if someone has plastic surgery, someone will say that he has plastic surgery behind his back. In fact, in Korea, some people can't see cosmetic surgery, just like fine-tuning. Generally good-looking people will choose fine-tuning, because there are not many places to move, just to make themselves more perfect before plastic surgery. But I think everyone has the right to pursue beauty. Maybe everyone pursues beauty in different ways, so we don't need to say some sarcastic words to those who have plastic surgery, because we expect the same result, but we want to be more beautiful.
Generally speaking, I think Koreans have a high degree of acceptance of plastic surgery. With the gradual improvement of medical and beauty technology, I think people from more countries will be able to receive cosmetic surgery.
I hope my answer can help you.
