The serum has a quick-breaking water effect in which drops of water are a part of the serum formulation. A physical reaction occurs when one spreads the serum onto the skin. The gel breaks apart and releases water droplets which cause a cooling sensation and feelings of freshness. As one continues to spread the formula, the water droplets evaporate stealing heat from the skin to even further decrease the skin's temperature. After the serum is applied, the skin is left with a silky-smooth feeling and a delicate, barely-there barrier that locks in moisture.
