It is hard to say that it has not been done at all. Nowadays, there are many stars who cut double eyelids, play hyaluronic acid and Botox, and even many stars in Chinese mainland and Taiwan Province have done it. And now that plastic surgery technology is advanced, this kind of minor surgery is basically invisible. Besides, South Korea calls it beauty, which is very common. However, there are still some stars who don't have major plastic surgery. Song Hye Kyo Jing's face hasn't moved, but I heard that she used to be very fat and lost weight by liposuction. Jin Taixi and Han Jiayin are one of the most beautiful women in South Korea.
