Hyaluronic Acid 2% + B5 Hydrating Serum with Ceramides

This serum combines several forms of hyaluronic acid with panthenol, also called pro-vitamin B5, plus a small amount of ceramides and phospholipids to support the skin barrier while it hydrates. The lightweight texture layers well under heavier creams. It's one of The Ordinary's most popular releases, an affordable, no-frills hydrator that suits most skin types.
