Bi-Phase Serum refines the skin’s texture and smooths its surface. Your quenched skin is fresh, comfortable, radiant, and vibrant. For even more hydration, Bi-Phase Serum can be used together with the Hydra-Essentiel cream suitable for your skin type. *The “sponge molecule”: the skin’s natural water retention system
