HUMskin is the name of a standardised technical skin model that should greatly simplify the development of cosmetic products in the next few years. HUMskin is based on a modified biopolymer and simulates the physiological, mechanical and topographic properties of healthy human skin. For example, the surface of the technical skin substitute material has a typical field structure and its pH value is similar to that of our skin, pH5.5 - slighdy acidic. The physiological parameters of HUMskin, such as moisture content and transepidermal water loss (TEWL), have also been made to match the known values for human skin.
