I did it around 2018, but it's been so long that I can only remember that the doctor in charge was a man. I think there was only one doctor at the time... I didn't sell my hands, and my younger brother did 3 types of contours in cookies, but it was big There was no problem, so I just followed it. The event was 700 won, but it was introduced by a younger brother who did a lot of things in Cookie, so I did it at half price again. After that, the pain was only a little right after the surgery, and I had a headache like a fever for a few days? I was very scared, but I only remember thinking that it didn't hurt more than I expected. Looking at the reviews of the 3 types of contouring, the face became slimmer and smaller as if there was almost no chin, but I didn't feel that dramatic effect. It hasn't changed to the level of other people, so there's less sagging .
