Hyaluronic Acid (HA) can attract up to 1,000 times its weight in water. The molecular size of HA determines its depth of delivery in the skin. This formulation combines low-, medium- and high-molecular weight HA, as well as a next-generation HA crosspolymer at a combined concentration of 2% for multi-depth hydration. This system is supported with the addition of Vitamin B5 which also enhances surface hydration. A more advanced HA formulation with 15 forms of HA, including precursors of HA, is offered by our brand NIOD in Multi-Molecular Hyaluronic Complex.
