Cosrx The Hyaluronic Acid 3 Serum 20ml

Cosrx The Hyaluronic Acid 3 Serum is a concentrated hydrating serum with 3% sodium hyaluronate — a clinical-grade concentration that plumps, hydrates, and reduces the appearance of fine lines. The formula goes beyond basic hydration with a skin-identical barrier complex: ceramide NP strengthens the lipid barrier, cholesterol and phytosphingosine mimic the skin's natural structure.

A comprehensive NMF (Natural Moisturising Factor) amino acid complex — including serine, alanine, glycine, threonine, arginine, proline, glutamic acid, and lysine — replicates the skin's own moisture system. Lactic acid provides gentle exfoliation. Sodium PCA and sodium lactate bind moisture at the surface. The result is a serum that doesn't just add water to your skin — it teaches your skin to hold onto moisture itself.

1. After cleansing and toning, dispense 2-3 drops onto your palm.
2. Gently pat and press across your face and neck.
3. Follow with moisturiser to seal in the hydration.
4. Use morning and evening.

Pro tip: The 3% concentration is notably higher than most hyaluronic acid serums (which typically contain 0.1-1%). Apply to slightly damp skin — hyaluronic acid is a humectant that draws moisture, so applying to damp skin gives it water to pull into the skin rather than pulling moisture out. The ceramide NP and NMF complex make this more than just a hydrating serum — it's a barrier-repair treatment. In dry or air-conditioned environments (common in the UAE), always follow with a moisturiser to prevent the hyaluronic acid from evaporating.
