What it does: This serum features the perfect combination of water-based and oil-based formulas to replicate skin's ideal hydrolipic film, which is the oil-to-water balance present in healthy skin cells. The superior dual-chamber system delivers a precise dose, releasing the perfect amount of formula that blends on contact with the skin.

How to use: Warm one drop of serum between your hands. Then, apply to a clean face, neck and chest with gentle pressing motions. Follow with your day or night moisturizer.
