Hyaluronic Acid: What It Does and How to Use It
Glow Ledger Editorial Team · Updated 2026-10-20
Hyaluronic acid is a humectant, meaning it attracts and holds water at the skin’s surface. Well-hydrated skin looks smoother and plumper, and fine lines caused by dryness can look softer.
Apply it to slightly damp skin and follow with a moisturiser to seal the water in. It suits most skin types and is a common first serum for beginners.
It supports hydration rather than replacing actives like retinol, so most routines pair it with other ingredients. Read our routine guide for layering order.
