Hyaluronic Acid: Exponent's hyaluronic acid stands out because it uses four different molecular weights to penetrate multiple layers of the skin, delivering deep hydration and an immediate plumping effect.

Pro-tip: Use it as a touchup before date night or a GNO

The HydroGlow Oxygen Ionizer is innovative because it uses a high-pressure chamber to activate oxygen with our best-selling multi-weight Quadruple Hyaluronic Acid Serum into a feather-light, ionized mist that draws in up to 1,000X its weight in water to instantly replenish hydration at and below the surface with a dewy glow finish.
