Hyalogic Episilk™ HA Lip Balm Stick with Hyaluronic Acid is formulated to plumpen and moisten dry, chapped lips. Young lips are smooth and highly elastic because they contain high concentrations of Hyaluronic Acid, which helps skin stay healthy. As we grow older, the body loses its ability to maintain this same concentration in the skin. The ability of the skin to retain water also declines with age. As a result, the skin becomes dry and loses its ability to restore itself. Without water, the spaces in the skin appear which leads to wrinkling and the older skin appearance. Hyaluronic Acid acts as a space filler by binding to water and thus restoring normal skin health.
