The stratum corneum is the visible part of the epidermis and is actually a layer of dead skin cells immediately on the skin's surface. This layer uses a protein called keratin to form a tough barrier between the outside world and the more vulnerable cells inside the skin and body.
The epidermal layer is the thinnest of the layers and is made up of its own set of thinner layers. The outermost layer is composed of keratin (a fiber protein) cells. These cells combine with a thin layer of oil to create a water-proof layer.
