It was done a month and a half ago . I have a face like Jung Chae-yeon. The sides are square, but the front looks slim. So I cut behind the ears and only cut the square ones behind the ears . It was a bone surgery, but nothing really hurt . Is that a bit harsh?? The big swelling went away after about a month. The area behind the ear was 2 cm. I cut almost all of it out. But, it is less scary than doing it in the mouth, and the recovery is much quicker. I ate rice the same day. I don't know, but the next day my mouth opened well, and I cut the cleft bone, and the recovery was very fast. And there were no side effects. But the important thing is that it's been a month and a half since I cut my chin. Does anyone know if it goes.... I really like the side line. It's slim without angles at all!!!!!!
