Mainly depends on what causes your chin hypertrophy. Generally speaking, there are three situations: large bones, too large occlusal muscles and too much fat. How to make your chin smaller needs to find your own direction. The only way to get big bones is to do bone grinding surgery, and the masseter muscle is big. Don't eat chewing gum at ordinary times, pay attention to eat less hard things, let the muscles slim down, or have a face-lifting needle; If you have a lot of fat, you should do more exercise, massage or liposuction. My friend had a face-lifting needle in Shanghai Meize Plastic Surgery Hospital, and the effect was quite good. After several injections, he obviously lost weight. Thin face is different for everyone. It's up to you.
