Virtual skin: a behavioral approach helps verification

The aim of this study is to develop a new kind of R&D methodology through a VHDL-AMS functional virtual prototype (FVP) applied to cosmetic industries. Cosmetic firms are in the process of improving R&D methodologies with more formal methods. These studies are mostly based on functional models and less laboratory testing. Hence, in cooperation with Lancaster firm, we have built for the first time a unique dynamic model of biophysical and chemical phenomenons linked to human skin and sun spectrum. Human health can be strongly influenced by exposure to solar radiation. Relevant interactions regarding to health take place mainly in the skin. So, the optics of human skin is of the utmost importance with reflection and absorption properties. By combining a sun emission light model and a bio-optical human skin model, we can compute the effects of the sun radiations on various species including free radicals generation.
