Found naturally in the skin, Hyaluronic acid helps your skin improve its ability to stay hydrated. This humectant works by providing an environment where water molecules bind and are retained in the layers of the skin. Hyaluronic acid has restorative abilities and can boost skin’s moisture content, soothe, and defend against moisture loss. It is capable of holding up to 1,000x its weight in water, making it one of the best hydrators for all skin types.
