Hydra Life Serum Sorbet is a lightweight serum that provides instant and lasting hydration, both at the skin's surface as well as deep within. The ultra-refreshing formula is two times more concentrated in Hydra Life's trio of plant extracts than the other products in the Hydra Life range for increased hydration, plumpness and antioxidant protection. Hydra Life Serum optimizes the flow of moisture throughout the skin, boosts collagen production and strengthens the skin's defenses against free radical damage. Skin is visibly more beautiful and better able to resist the effects of stress and fatigue. 1 oz. By Dior.
