Our body naturally produces Hyaluronic Acid and contributes to the skin's natural health, aiding in wound healing, keeping the skin youthful, providing long lasting hydration, maintaining the supple softness of the skin and structure. Hyaluronic Acid retains moisture in the skin as it can hold up to1000x its weight in water. When the skin holds moisture the skins cells bind together keeping the firmness and elasticity of the skin strong. Hyaluronic acid acts as a cushion for the tissues which is how we keep our skin lovely and plump.
