Oriental women should have a soft, rounded facial contour, but some women’s facial lines are not like that. The most common type of face is the square-shaped face, which is caused by a large bilateral mandibular angle or an enlarged biting muscle. Its width as well as the structure of the line is a direct cause of whether the face is square or not. In addition to its innate width, the jaw angle is also affected by chewing habits that change its shape, so people who like to chew slowly or those who like to eat hard food will also make the jaw angle more developed and the square face more prominent. Nowadays, there are different methods to improve and adjust the curve and shape of the face according to the shape of the patient’s face and the bones of the face, which can successfully correct the square face, high and prominent zygomatic bone, crooked face, short chin, long chin and other kinds of lack of beauty, and change the shape of the face out of the curve is clear, harmonious and perfect.
