The medical beauty in Taiwan Province Province is indeed more mature and developed. Saitama Medical Beauty is from Taiwan Province Province. I am a doctor of Saitama Medical Beauty. I usually follow the following five principles: (1) Primary and secondary principle: Before designing a face, find out the main problems and secondary problems. Generally, the main problem is often the biggest change, and the secondary problem is the icing on the cake; (2) the principle of wholeness: beauty pays attention to the coordination and unity of the whole, not the single beauty. Even if the eyes are beautiful and the nose is beautiful, if the proportions are not harmonious, they are not beautiful together; (3) Aesthetic standard principle: such as three courts and five eyes, three points and one line from the tip of the nose to the lip to the mandible, nose frontal angle of 30 degrees, nose columella at right angles to the upper lip; (4) Principle of reversibility first: Try to design a reversible treatment scheme and avoid surgery as much as possible. (5) Personality principle: Beauty has standards, but it is not unique. Personalized comprehensive design is the future development trend.
