The structure of the structure can be divided into three layers: epidermis, dermis and subcutaneous tissue.
The epidermis is the outermost layer and consists of the stratum corneum and the transparent layer. The stratum corneum is made up of dead keratinocytes that prevent water loss and the invasion of foreign substances. The transparent layer is a thin layer under the stratum corneum, which can refract light and make it look brighter.
The dermis is the middle layer of the dermis and is made up of connective tissue, which contains a large amount of collagen and elastin fibers. These ingredients make ** have a certain elasticity and tension, and also contain nerves, sweat glands, sebaceous glands and other organs. The thickness of the dermis varies from individual to individual and site, and can affect the elasticity and texture of the dermis.
The subcutaneous tissue is the innermost layer and is made up of fat and connective tissue. The main function of this layer is to keep warm, cushion external forces, and store energy. At the same time, the subcutaneous tissue also contains a large number of blood vessels and lymphatic vessels, which provide nutrients and excrete waste.
