The skin is composed of two tissues, an outer layer called the epidermis and an inner layer called the |dermis| or corium. The surface of the skin, or the epidermis, consists of dead cells, which are rubbed off as you move, wear clothes, and wash. This layer of dead cells is often refered to as "false" skin. Just below, in the |dermis|, the cells are very much alive. The cells of the |dermis| multiply every second to replace those worn away. The epidermis consists of four layers: the |stratum basale|, the |stratum spinosum|, the |stratum granulosum|, and the |stratum corneum|.
