Although it is difficult to set a uniform standard for beautiful appearance in numbers or words, there are some common characteristics. Facial beauty is mainly reflected in three aspects: contour, features and skin, and Botox can play a beautifying or rejuvenating role in all three aspects. A beautiful face requires a properly proportioned bony profile and moderately plump soft tissues. Facial contour beauty is expressed in clear lines, roundness and fullness, concavity and convexity, oval shape, moderate length to width ratio, etc. Botulinum toxin injection can change the facial contour, mainly in the following aspects: bite muscle injection can reduce the width of the lower third of the face, making the facial contour more perfect; chin muscle injection can increase the length of the chin, thus improving the chin contour; descending nasal septum muscle injection can raise the tip of the nose; broad neck muscle injection can increase the clarity of the jaw contour. 2, the five senses constitute the facial features of a person, and the beautiful five senses include the beauty of individual organs and the coordinated beauty between the five senses. The shape of individual organs needs to conform to their respective aesthetic standards, such as large eyes, high nasal bridge, etc.; the position and proportion between the five senses also need to conform to the aesthetic standards of the face, such as “three chambers and five eyes” and left-right symmetry, etc. The precise injection of Botox in some specific areas can adjust the shape and position of facial features, such as changing the position of the eyebrows, increasing the cleft of the eyes, improving the gingival smile, lifting the corners of the mouth, elevating the tip of the nose, adjusting the asymmetry caused by facial muscle spasm and other deformities, and play a role in beautifying the features. 3. Skin is the outermost tissue of the human body. After having a perfect outline and features, it needs healthy skin coverage to form a beautiful face, and since ancient times in China there has been the saying “a white cover a hundred ugly”, which shows the importance of skin to beauty, the beauty of the skin is mainly reflected in the color and texture of two aspects. The most important contribution of Botox to skin beauty is wrinkle removal. For various dynamic wrinkles on the face, Botox can be injected into the corresponding muscles to solve them. In addition, after Botox injection, the skin texture will significantly improve and the shine will increase significantly, this phenomenon is more prominent in the Oriental people, and even become one of the main purposes of Botox injection for many beauty seekers.
