Hyaluronic Acid is a humectant that draws water from the environment and deeper skin layers, holding up to 1,000 times its weight in water. This boosts surface hydration and reinforces the skin’s natural barrier, preventing transepidermal water loss. However, HA molecules tend to be large molecular weight, sitting on the surface of the skin, which can be irritating and less effective. A Quadruple weight HA will use multiple weights for more even penetration.

Benefits: intensely hydrates for a plump, dewy, full finish and feel.
