First, the aesthetic standards of the face Standard facial shape, its length and width ratio is coordinated, in line with the three stops and five eyes. Three stops refers to the length of the face, the distance from the hairline of the head to the chin is divided into three equal parts, that is, from the hairline to the eyebrows, eyebrows to the tip of the nose, the tip of the nose to the chin is divided into a first part, each called a stop a total of three stops; five eyes refers to the width of the face, the length of the frontal projection between the ears is the length of the five eye fissures, except for the eye fissures, the spacing within this is the length of one fissure, the outer canthus on both sides to the ear has a fissure length, which is the length of the five eyes called five eyes. The lower lip height is about 1.618 of the upper lip height (in accordance with the golden rule). Angle relationship: The human form reflected from different angles varies, and the lateral angle theory proposed by Belt and Campen, etc. is to reflect the beauty of the human form through the angle. Campen’s doctrine is a method of measuring the tilt angle of the forehead when viewed from the side by using the straight line connecting the point under the nose and the point of the ear hole as a reference, so that the complex three-dimensional sense of the head can be described by a simple contour line – known as the side qualitative analysis method. A straight line connecting the tip of the nose and the point under the chin is used to observe the prominence of the lips and to evaluate the beauty of the lower part of the face. The tip of the nose, the front edge of the lower lip red, and the point under the chin are on the same straight line, called Ricketts aesthetic plane, a sign of beauty.

Third, facial plastic surgery methods 1, surgical methods, mainly including skeletal plastic, in addition to include soft tissue fat suction, is said to be liposuction. 2, injection methods, the most used is the injection of carnitine, it is mainly for the bite muscle, mainly is to inhibit the nerve innervation of the bite muscle, so that this muscle gradually atrophy, for the bite muscle hypertrophy of the face has a significant effect. 3, filling methods, materials including their own qualities, such as their own free fat, in addition can include some applications of biological materials, such as artificial bone, or tumescent, silicone can be used.
