The hospital was fairly close to Exit 7 of Sinnonhyeon Station, so I could find it right away, and the interior felt well organized too. I waited a little and then went in.
The consultation was not just one where they set a double eyelid line and ended it. They carefully checked my existing double eyelid height / horizontal eye length, and how much of the iris is visible in my eyes.
They said they would release the adhesion of my current double eyelid line, and for revision surgery, they recommended an incisional method.
Based on the review booklet I saw while waiting and the app reviews, the line they create is closest to my taste, so I’m considering revision surgery there.
