I only wanted to remove the corners behind my ears, so I didn't touch them much and only had a square jaw surgery, but it's already been 8 years. If I talk about my 8-year review, I'm satisfied because it has a natural look that only I know. Since I only removed the corners behind my ears, the muscles and such are managed with botox, so my face shape has definitely become much smoother. As for sagging and such, it seems that there is no particular problem other than natural aging that occurs in your 30s after 8 years. When I touch it, the area where my square jaw was isn't 100% healed, but it feels like only about 90% is there. But it's not enough to worry me too much (I'm a bit indifferent) . There were no particular side effects, and it's a satisfactory surgery because I didn't touch my contour because I was greedy.
