The Ordinary Hyaluronic Acid 2% + B5 is a hydration support formula featuring ultra-pure, vegan hyaluronic acid combined with vitamin B5. This lightweight serum uses multiple molecular weights of hyaluronic acid for multi-depth hydration and visible plumping effects on the skin. Key features: • Contains 2% hyaluronic acid in multiple molecular weights • Enhanced with vitamin B5 for added hydration • Vegan and cruelty-free formula • Lightweight, water-based serum texture • 60ml larger size bottle • Suitable for all skin types The formula combines low-, medium- and high-molecular weight hyaluronic acid along with a next-generation HA crosspolymer to provide hydration at multiple skin depths. Unlike traditional HA products that may only provide surface hydration, this advanced system ensures deeper penetration without drawing moisture out of the skin. The addition of vitamin B5 (panthenol) helps enhance surface hydration and skin barrier function.
