I had my first surgery done here, and after about 5 to 6 years it gradually started loosening from the ends. Time passing can also cause eyelid skin to sag, but apart from that, the line itself simply became invisible and loosened.
Still, it was legendary-level natural. Even though it was a buried suture method, there was not even a trace left. Even with my eyes closed, nobody could tell. But in the end, it did come undone. I am not sure if it was because they were pursuing a natural look, but it loosened so I had a revision elsewhere. And back then they also said they would do eye correction, but they did not do it (why?). I paid exactly 1 million won at the time, and I guess that was the price without eye correction included.. Maybe? That has always been a question for me.
I went back asking whether I could get a revision once because my double eyelid had come undone, but the coordinator just said it was due to sagging skin, and I got cut off at the coordinator stage without even meeting the director.
