Synopsis The mechanical properties of stratum corneum and epidermis have been measured in vitro and a dispersity of approximately 30% to 50% between samples from the same donor has been found. To overcome such a limitation, a technique was developed in order to compare the mechanical properties of the same skin sample before and after treatment. The chosen parameter (initial slope of the stress‐strain curve) appeared to be influenced by the topical application of products. A different time response was found with stratum corneum and epidermis reflecting their structural differences.
