From the clinical point of view, the appearance and facial contour are mainly influenced by the structure and morphology of hard and soft tissues. The so-called hard tissue is bone, and the mandibular angle and cheekbones have the most obvious influence on facial contour. Soft tissue includes skin, muscle, subcutaneous fat, buccal fat pad, masseter muscle and so on. Face-lifting is actually the main purpose of repairing facial contour by adjusting the height and thickness of soft and hard tissues. Cosmetic surgery is the most direct and effective way to repair and reshape the face, and different facial plastic surgery methods can be selected according to different face types and requirements.
