Beauty is to maintain the integrity, compactness, elasticity and luster of the skin. The density of skin directly affects the sealing and sealing function of skin. If the compactness is poor, its sealing ability is insufficient, which will cause the loss of qi, blood, body fluid and abnormal phenomena such as hyperhidrosis. Insufficient sealing ability can easily lead to the invasion of exogenous pathogens and damage meridians and viscera.
