The thickness of the epidermis, the dimensions of keratinocytes and the surface areas of individual corneocytes were measured in normal human skin from 3 non-light exposed sites. The numbers of cells in the epidermis and their height decreased with age; the surface area of individual corneocytes tended to increase with increasing age. The changes demonstrated may be responsible for the alterations noted clinically in the skin of elderly individuals.
