Why do Korean men and women have plastic surgery? Are they too fond of beauty or too pretentious?

this has something to do with our cultural differences. Most people in China think that everyone has his own appearance, whether it is good or bad, it always has his own specific meaning. However, I don't know much about the specific culture of Korea, but most Koreans are dissatisfied with their looks and go back for surgery in high school. Of course, there is another kind of cosmetic surgery they say, that is, micro-cosmetic surgery, that is, not using a knife, just doing beauty and the like, or skin replacement surgery is not a major operation. Plastic surgery is actually a new medical project that has become popular in China. But Korean boys' plastic surgery, in the final analysis, may be due to k-pop. Their idol culture makes them have to cover up some small defects or flaws on their faces by surgery.
