Hyaluronic acid is a carbohydrate molecule that is produced naturally by our bodies. Within skin, hyaluronic acid functions by binding water to collagen and retaining that moisture. Collagen forms the structure of the dermis, and hyaluronic acid supports it in maintaining skin plumpness and bounce. The skincare industry commonly uses hyaluronic acid for skin hydration, as the ingredient is especially effective at drawing in and retaining water content.
As a humectant, hyaluronic acid promotes the absorption and retention of moisture. Able to hold up to 1000 times its own weight in water, hyaluronic acid in skin care encourages optimal hydration levels and is suitable for all skin types.
