This lightweight serum provides instant and lasting hydration, both at the skin's surface and deep within the skin. The ultra-refreshing formula is two times more concentrated in Hydra Life's trio of plant extracts than the other product in the Hydra Life range for increased hydration, plumpness and antioxidant protection. Jisten optimizes the flow of moisture throughout the skin, Centella boosts collagen and Black Rose strengthens the skin's defenses against free radical damage. Fully hydrated, plumped and reinforced, skin is visibly more beautiful and better able to resist the effects of stress and fatigue.
