Hyaluronic acid is a naturally occurring polysaccharide that holds up to 1000x its weight in water, drawing moisture into the stratum corneum. It works as a humectant, improving skin hydration and creating a plump, dewy finish. Molecular weight variants (high vs. low) penetrate to different skin depths, with lower weights reaching deeper layers.
