Abstract
A method of profiling skin comprises comparing the rugosity and/or the length of rete ridges beneath the skin relative to a length of skin and optionally also the relative thicknesses (or volumes) of the dermis and the epidermis. The method allows for determination of the ability of a cosmetic formulation to hydrate or “plump” skin.
