In this feasibility study, changes in the elastic properties of skin following various skin treatments (e.g. water, skincare ingredients, etc.) were investigated using a new in vivo tensile testing method. The properties of human skin in vivo , and in particular the properties of the stratum corneum, were studied using a combined experimental‐numerical approach. Tests on a small number of volunteers indicated that the in vivo testing method was sensitive to the effect of skin treatments and could distinguish their relative performances. The ingredients tested effectively made skin less stiff. Preliminary results showed that stratum corneum is highly anisotropic and that the data was in general agreement with some but not all published in vitro results, although this is the first time ever that Poisson ratios for human stratum corneum are presented.
