Hyaluronic Acid Elastomer (Hyacross), new member of HA family, is a crosslinked polymer derived from natural HA. It appears like an elastic gel with high viscosity, feels smooth but not sticky. The mesh network structure of Hyacross is observed by scanning electron microscopy. So it is able to form invisible biological film on the skin surface with various effects, such as improving the skin barrier function, reducing the water evaporation from cuticle, long-lasting moisturizing, improving skin elasticity, protecting skin against UV and external pollution, etc.
