Quench your skin’s thirst with COSRX The Hyaluronic Acid 3 Serum — a luxurious serum formulated to deliver intense hydration while preserving elegance. With 3% hyaluronic acid (low molecular weight), ceramide NP, and a complex of natural moisturizing factors, this serum deeply hydrates, plumps up fine lines, and strengthens your skin barrier. The texture is lightweight, non-greasy, and absorbs swiftly for skin that feels soft, dewy, and beautifully resilient. Perfect for AM or PM, especially when your skin is feeling tight, dull, or parched. ✨

Key Features:

  • 💧 3% Hyaluronic Acid for deep hydration and plumping effect.

  • 🌿 Natural Moisturizing Factors (NMF): amino acids, PCA, sodium lactate & more to mimic skin’s own hydration system.

  • 🛡 Ceramide NP + barrier lipids (cholesterol, phytosphingosine, etc.) to support and protect the skin barrier.

  • ✅ Lightweight, fast-absorbing texture; suitable for all skin types, especially dry, dehydrated or sensitive.

Cleanse your skin and optionally apply toner or essence.

Take a few drops of the serum, and apply to slightly damp skin, starting from the center of your face outward.

Gently press or massage in until fully absorbed.

Follow with your moisturizer (and sunscreen in the morning).

Use both morning and evening for optimal hydration.
