Plastic surgery is big in SK to the point where getting little things (like double eyelids) are pretty common. Wealthier parents even "gift" their daughters those things and nose jobs before they enter college as a way to help them meet potential partners/ get jobs faster. The working culture there is big on appearance and when you go by certain businesses there, bosses put all the attractive employees up front.
When you walk through Gangnam, you will see plastic surgery advertisements everywhere along with foreigners covered in badages since they came for plastic surgery (especially from China). There is even a term "Gangnam Face" with the chin shaved, undereyes puffy, and lips super full.

The current trends are the "V" face with big eyes, long nose, and pointed chin that gives them the illusion of having doll faces. A lot of the line models there have an uncanny valley look to them that only look good in heavy filters.
