The Ordinary Hyaluronic Acid 2% + B5 is a lightweight serum that combines low, medium, and high molecular weight hyaluronic acid, along with vitamin B5, to offer multi-depth hydration and visible plumping without drawing water out of the skin solely to improve temporary surface hydration. This advanced formulation is enhanced with vitamin B5 to provide surface hydration, aiding in skin repair and anti-inflammatory benefits. Hyaluronic acid attracts up to 1,000 times its weight in water, making it an excellent hydrator for all skin types. The serum works to replenish moisture levels, leaving the skin looking smoother, softer, and healthier. The non-greasy formula absorbs quickly, making it suitable for daily use as part of your skincare routine.
