Hyaluronic Acid (HA) can attract up to 1,000 times its weight in water. The molecular size of HA determines the depth of its delivery into the skin. This formula combines low, medium and high molecular weight HA, plus the next generation HA cross-polymer at a 2% concentration for multi-depth hydration in a water-based formula. This system is supported by the addition of Vitamin B5 which also enhances surface hydration. This product does not have a safety seal.
