How to correct these problems, we must first know what causes them. Round face is generally the accumulation of facial fat, which leads to the concentration of facial fat. Square face and diamond face are generally caused by facial masseter hypertrophy. They like chewing gum and often eat hard-to-chew foods such as nuts. If you want to face-lift, you should keep your mouth shut, avoid eating hard food at ordinary times, reduce the frequency of chewing food in your diet and slow down the frequency of masticatory muscle movement. Reducing the amount of activity will gradually decrease, but it takes a long time to chew muscles. I suggest you eat Yan Jia fruit, which is rich in potassium. By chewing and infiltrating the face, generally eating a round face for a month or two will lose a lot of fat faces. If it is a square face, it will take a long time, but it is much faster than massage to lose weight.
