Facial contour shaping, commonly known as facial modification, refers to changing the facial contour through modern cosmetic plastic surgery technology to make it close to aesthetic standards or ideal appearance, and carving the face lacking aesthetic feeling into a pleasing and beautiful appearance. Craniofacial deformities caused by trauma such as car accidents can also be restored (close to) normal appearance by this technology. In recent years, with the improvement of living standards, facial contour shaping technology has developed rapidly in the field of plastic surgery.
