Stratum corneum is a tough and almost impermeable outer layer of the body, consisting of about 20 stacked layers of corneocytes. The corneocytes are the end product of the keratinocytes, which are continuously produced in the basal layer of the epidermis. The loss of single corneocytes at the skin surface (desquamation) takes place in a controlled manner, in which proteases are involved [1]. At equilibrium, the rate of epidermal cell production corresponds to the loss of desquamative cells, although the details of the link between these two parameters are obscure.
