I do not remember the exact price, but around Seomyeon, Busan, it was almost the same as the quote I got for an incision procedure at a plastic surgery clinic. I remember it being cheaper after a discount (this was almost 5 years ago). The person doing the consultation was ordinary, and the doctor also gave a pretty standard consultation, but they did not make any pushy recommendations. The location is convenient, the clinic is small, and there are surprisingly many people.
I had an incision procedure, but one side loosened, so they did a follow-up correction. I also had ptosis correction, and that seems to have turned out better. They did not make the line too dramatic and pursued a natural look. It was a good clinic for a straightforward double-eyelid surgery.
