The Ordinary Hyaluronic Acid 2% + B5 is a hydration support formula featuring ultra-pure, vegan hyaluronic acid combined with vitamin B5. This lightweight serum delivers multi-depth hydration using three molecular weights of hyaluronic acid and an HA crosspolymer at 2% concentration for optimal skin plumping and moisturizing benefits. This water-based formula combines low-, medium- and high-molecular weight hyaluronic acid along with a next-generation HA crosspolymer to provide hydration at multiple skin depths. The addition of Vitamin B5 enhances surface hydration. The product should be applied as a few drops to the face morning and evening before creams. As with any skincare product, patch testing is recommended before first use. The formula is packaged in a 30ml bottle with a dropper applicator for precise dispensing.
