I think what people are usually curious about is the cost, effect, and recovery period, so I’ll talk very briefly about those three based on what I felt.
I had eye surgery at a place in Gangnam that isn’t famous. The cost was also affordable, between 1 and 1.5 million won. It wasn’t a famous place, but the director felt like Lee Sung-min’s character in Golden Time... like, wow, he’s really a doctor.. (just my personal thought)
I didn’t want eyes that looked too intense, so I repeatedly begged the director to please make them look natural... natural. Maybe because of that, it doesn’t look excessive and seems to have just the level of effect I like.. If you’re someone who can confidently walk around saying, “I got plastic surgery!!!” then going dramatic is fine, but most people can’t do that.. so I recommend doing it naturally.
First of all, it’s very uncomfortable. You have to apply a lot of ointment too.. and without realizing it, your eyes get itchy and you scratch them with your hands... then there can be inflammation too.. You need to put up with the discomfort for about a week.
