<P> Epidermis is divided into several layers where cells are formed through mitosis at the innermost layers . They move up the strata changing shape and composition as they differentiate and become filled with keratin . They eventually reach the top layer called stratum corneum and are sloughed off , or desquamated . This process is called keratinization and takes place within weeks . The outermost layer of the epidermis consists of 25 to 30 layers of dead cells . </P>
