Epidermal 'turnover time'--a new examination.
A new model for assaying epidermal cell turnover times is presented. It is based on desquamation rates of the stratum corneum and the consequent obligatory turnover time of the keratinocyte layer. A total epidermal turnover time of 45 days is derived from the model for the human volar forearms.
