First, get rid of the habit of eating at the same time. If you used to eat with your left mouth for a long time, you need to eat with your right mouth from now on until your face is symmetrical, and then you need to eat with both sides. If you eat with one mouth for a long time, the face you often use will look big and your muscles will develop. If so, it will look ugly, especially for girls, which will affect the appearance.
Second, you can massage your face. Pat the side of your face that you often use every day, and pat it when you have nothing to do. Sticking to it for a while will definitely have an effect. I have a classmate whose calves are thicker than thighs, which is no exaggeration. Later, in order to wear a skirt, she beat her legs for half an hour every day, and her legs were bruised. Finally, her calf was reduced. This method can also be used to thin face, because the meat on the face is tender, so you should pat it gently.
Third, when you sleep, you can hold down your fat face with the posture of sleeping on your side, which will also reduce your face. Hold the fat face down and the other face will grow freely, which will gradually become more symmetrical.
Fourthly, if you don't want to use any of the above methods, I think you can take acupuncture weight loss's method and cut off the side of your face where you often eat. But I heard that acupuncture is easy to rebound. You can try it and see how it works.
In order to be beautiful, you must be hard on yourself. If you always want to be lazy, then you can continue to be ugly.
