The HydraFlex Blend adapts to your changing environment to give your skin the right hydration no matter where you are because it’s amphiphilic, which means that it contains both water and oil-loving components. The water-loving portion retains water on the skin, while the oil-loving part prevents evaporation. This allows the blend to auto-adapt to your changing environment, drawing in moisture and preventing evaporation as needed to allow your skin to have just the right amount of hydration.
