Note: Hyaluronic Acid is found in the skin naturally but its natural function within the skin is not hydration. Many products have use HA to claim hydration benefits, but HA is too large of a molecule to penetrate the skin and instead sits on the surface and can draw moisture out of the skin making the surface feel soft and hydrated temporarily, while making you feel like you need more HA after the product is rinse. This formula uses three forms of HA with varying molecular weights, as well as an HA cross polymer, to offer multi-depth hydration and visible plumping without drawing water out of the skin solely to improve temporary surface hydration.
