Dry- to normal-skin cleanser intuitively rehydrates skin. Hygroscopic (water-attracting) moisturizers are encapsulated into nano-spheres, barely wider than a ray of light. Self-activated spheres burst when released onto the skin surface, breaking apart surface debris like makeup and dead skin. However, a small percentage of the spheres remain just beneath the skin's surface, actually replacing the moisture typically lost during cleansing.
