Generally, the contour of the face forms the basis of a person's overall image.
So, let us think about how facial contours are determined.
First, the main foundation of facial contours is determined by the facial bones, and the final facial shape is determined by the soft tissues surrounding the bones.
If we look at these facial bones, they consist of the cheekbones, which are responsible for the contour of the midface (the middle part of the face), and the lower jawbone, which is responsible for the contour of the lower face; the upper part, including the forehead, is made up of the skull.
Meanwhile, the soft tissues covering the facial bones consist of muscles, a subcutaneous fat layer, and skin.
Among the muscles covering the bones, the masticatory muscles covering the lower jawbone play a major role in forming the contour of the lower face, and the thickness of the fat tissue between the muscles and the skin itself also has a major effect on facial contours.
Among the soft tissues covering the cheekbones, which are responsible for the contour of the midface, the buccal fat covering the body of the cheekbone plays a role in making the contour of the anterior cheekbones, which protrude forward in the midface, stand out more prominently.
On the other hand, the contour of the lower face may appear larger not only because of the lower jawbone and the masticatory muscles covering it, but also because of the thickness and degree of development of the cheek fat and other lower facial fat.
