Five different types of hyaluronic acids are combined in this highly concentrated serum to help hydrate and fill in wrinkles. Why is it unique? ✏ A special blend of five distinct forms of hyaluronic acid (high, medium, and low molecular weight) and ceramides. ✏ The ideal combination of the five hyaluronic acid types allows for increased efficacy because they plump up wrinkles and increase hydration in all layers of the epidermis, from the inside to the outside. The skin has a velvety texture that absorbs quickly, leaving it looking and feeling younger, more hydrated, and smoother. 30 ml of serum for all skin types, daily use, and topic use
