Stratum Corneum
The top layer of skin called stratum corneum, or keratin, is composed of several layers of flat dead cells and acts as a barrier that protects the underlying fabric of possible injuries and infections. By reducing evaporation, the oils of this skin layer helps to maintain moisture in the deeper layers, maintaining the texture of the skin soft and supple.
The stratum corneum is only part of the epidermis, a thin layer of skin that covers almost the entire body. In some areas, like the palms of the hands and feet of plants, the skin is thick and the stratum corneum provides extra protection against impacts and abrasions. The skin can also be thick and hard in areas too dry.
The diseases of the upper layers of skin concern to the stratum corneum and the deeper layers of skin and can cause discomfort from a temporary grave until chronic disorders.
