Hyaluronic Acid 2% + B5 is a next-generation moisturizing serum from The Ordinary. It is formulated with five forms of hyaluronic acid, ceramides, and provitamin B5, delivering immediate and long-lasting hydration for skin that appears softer, smoother, and healthier. The lightweight texture absorbs quickly, leaving a non-sticky finish and supporting the skin barrier to improve the appearance of dryness and fine lines over time. Ceramides help maintain the moisture barrier, while five types of hyaluronic acid attract and retain hydration across multiple layers of the skin. Provitamin B5 supports overall skin comfort.
