The skin is organized into two main layers, the epidermis and the dermis , each comprised of specialized cell types that contribute to the unique properties of the layer. The epidermis is composed of keratinocytes in varying states of differentiation and primarily serves a barrier function, preventing water loss and invasion by microbes and toxins. The main function of the dermis, which consists mostly of Collagen and elastin, is to provide physical and nutritional support to the epidermis.
