The Ordinary Hyaluronic Acid 2% + B5 Hydrating Serum

A next-generation hyaluronic acid serum that gives an instant plumping effect and long-lasting, multi-layer hydration. Five forms of hyaluronic acid deliver smoother, firmer skin, while ceramides strengthen your skin barrier and help prevent moisture loss.
