The epidermis is a keratinized, stratified pavement of epithelium that is about 90% keratinocytes. Each of these cell types contributes to protecting the body against external attacking factors (the weather, ultraviolet rays, tobacco, etc.). Natural human epidermis is composed mainly of three types of cells, namely keratinocytes, which form the vast majority, melanocytes and Langerhans cells. The epidermis, which covers the dermis and is in direct contact with the external environment, has the main role of protecting the body against the dehydration and external attack. These components are synthesized by the fibroblasts. The dermis is composed mainly of fibroblasts and an extracellular matrix of collagen, elastin, and a substance known as ground substance. The dermis provides the epidermis with a solid support. Human skin is made up mainly of two main layers, the dermis and the epidermis, which superficially covers the dermis. Skin acts as a natural barrier between internal and external environments and therefore plays an important role in vital biological functions such as protection against mechanical and chemical injury, micro-organisms, and ultraviolet damage.
