As long as they feel that they need to improve, both men and women can go for plastic surgery.
When my sister was studying in Korea, she even found that the way Korean parents encouraged their children to study hard was to send their children for plastic surgery if their grades were good. It can be seen that cosmetic surgery occupies a very important position in the daily life of Koreans.
However, not every Korean has had plastic surgery. After all, beauty is born, and not everyone needs plastic surgery!
