To assess the moisturizing effects of a cosmetic product, IEC proposes to measure the skin electrical capacitance with a recognized technique [CorneometerTM CM825, C&K], associated with a 3 D mapping of Facial color [Newtone Analysis] also feasible on Trans Epidermal Water Loss [TewameterTM, C&K];

these techniques can be supplemented by the evolution of the 3-D parameters of the roughness of the skin surface with the newly acquired  10 Megapixels (UHD) Dermoscope sensor [C-CubeTM, Pixience].

These different techniques can be carried out during multicenter studies on 3 ethnic groups [Caucasian: France (Lyon, Saint-Etienne), Bulgaria / Asian: Japan, Singapore, Korea, China / Black African: South Africa] under controlled (kinetic) and / or real conditions (in Use Test).
