“The nose is the most prominent part of the face, and defects in the appearance of the nose will leave an extremely bad impression on people. Every beauty lover is eager to have a beautiful and graceful nose, showing the charm of the nose. The importance of nose beauty is self-evident. The Oriental nose has always been a recognizable mark: short, low, wide, with exposed nostrils and a large round nose. To put it simply, it is not obvious, and the goal is to become more refined and three-dimensional. So what kind of nose can be considered “beautiful”? There are several criteria: 1, three equal standards: facial trichotomy is also one of the classical aesthetic standards, called “three chambers and five eyes” law in China. Three-part method only for the face, the upper part from the frontal hairline to the arch of the eyebrows, the middle part from the arch of the eyebrows to the bottom of the nose, the lower part from the bottom of the nose to the bottom of the chin, modern aesthetic research has also confirmed the objectivity of the three-part method. The length of the nose is equal to 1/3 of the length of the face, and the width of the nose should be 1/5 of the width of the face, close to this ratio of the nose has a coordinated beauty. 2.Golden ratio standard: The golden ratio of each part of the nose is 0.618 between the length of the nose and the frontal end and the length of the nose; 0.618 between the width of the nose and the width of the lips; 0.618 between the height of the nose and the width of the nose; 0.618 between the height of the tip of the nose and the width of the nose; the golden section point from the frontal hairline to the vertical line of the tip of the nose is the best starting point for the root of the nose; the external nose close to this ratio has coordinated beauty. The purpose of the above standards is to reduce the differences between the physician and the candidate’s perception, and can be used as a reference point before surgery, increasing the key to determine and find out the core of structural problems before plastic surgery, rather than subjective errors based on intuition, but it does not mean that the nose is beautiful when it meets the standards, it is also closely related to the other facial features of the candidate and even personality and temperament.
