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,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.
