The whole face is flat when viewed from the side. That's because your facial features are not three-dimensional, so it looks flat. However, China people's faces are like this, and they are not as three-dimensional as those in western countries. Another reason is that there is more meat on your face, which will also weaken the three-dimensional sense of your five senses. It's best to slim down your face, so that the three-dimensional sense will be enhanced and it will look better. Your face is probably in good shape and has a chin, so as long as you can slim down the meat on your face, you can do it. You can go online to learn some face-lifting exercises and massages, which can help face-lifting, but the effect is slow. If you want a quick, healthy and safe method, then eat a pretty slim face-lifting fruit every day, so that you can lose weight more quickly and effectively.
