[0002] Skin is the body's natural barrier, which protects the body in various ways. The skin can be divided into the epidermis, dermis and subcutaneous tissue; among them. The epidermis assumes the barrier function and directly reflects the skin condition; the dermis is related to wrinkles, sags, etc.; the dermis has a certain density, and the higher the density, the stronger the adhesion of each layer of tissue, and the more elastic and firm the skin; with age and environmental changes, skin cells age and become more damaged, the fibers inside the dermis break, cavities appear, the density decreases, the skin function weakens, and wrinkles, nasolabial folds, sagging skin and other aging phenomena become more and more serious.
