I have a lot of friends who got double eyelid surgery at Busan D-P-S, Busan O-R-S, etc. Among them, I think O-H-S did the best, so I made my younger sibling do it there too. I had eyes that had all the bad conditions, but I think I got eyes that shouldn't have been possible. It turned out really well, but the scar on the front is a bit... but I think it's worth it. I did everything I could except for the bottom eyelid surgery, and it cost about 200, so it was worth it.
