The Rehydrating Serum is a lightweight, watery serum that refreshes the skin as soon as it is applied. It combines a Molecular Patch (three moisture-attracting biopolymers that release hydration gradually), Rehydrating Ferment from extremophile plankton, and high-molecular-weight hyaluronic acid. With regular use, skin looks plumper, more supple and more luminous. The formula has 96% natural-origin ingredients and suits all skin types, including sensitive skin.
