(1) lose weight. Losing weight does not mean losing weight, but body fat. Go to the gym every day for aerobic exercise+strength exercise to lose body fat quickly. This can account for 80% of the factors. You can search Dicky Cheung and Huang Lei on the Internet, and this is what they look like now. Compared with when I was young, when I was a boy, it was a far cry from it. When I was a teenager, the profile of my face was clear.

(2) Correct standing posture and sitting posture. Long-term low-headed people, sitting on the computer, have slight deformation of cervical vertebra, which needs to be corrected as soon as possible. You should also do a series of exercises regularly to pull the cervical vertebra back. There are many tutorials in this field on the Internet. You can watch it every day and do some exercise.

The above can completely solve your problem. If you want to pursue perfection, you must lay one or two foundations first, and then look at the third one.

(3) Injection pad chin. It depends on your personal data. You can stretch your chin down or forward. But personally, I think it would be nice to finish one or two. The third is not the main thing, just the icing on the cake.
