Hydration

Water is in constant flux within the epidermis of a healthy skin. Its evaporation and excretion are as natural as breathing; its optimal balance essential to healthy, radiant skin.
Hyaluronic acid and other epidermal structural elements, like ceramides, create a reservoir of water necessary for biochemical reactions and the healthy appearance of the skin.
A good state of skin hydration is a dynamic target, a microcosm of numerous biochemical factors working in synergy, each within its own system of precarious balance.
