The skin is divided into three layers, from the outside to the inside into the epidermis, dermis and subcutaneous tissue.
1. Epidermis: It is further divided into five layers, including the stratum corneum, which can protect the skin; the transparent layer, which can play the role of shock absorption, protection, and friction reduction; the granular layer, which can be waterproof and ultraviolet radiation; the echinocellular layer, which can store water, maintain the elasticity of the skin, and absorb nutrients; and the basal layer, which can play a role in regeneration and repair.
