The COSRX Hyaluronic Acid Hydrating Serum is a lightweight moisture-boosting serum designed to deeply hydrate and improve skin softness. Formulated with sodium hyaluronate (hyaluronic acid), it helps attract and retain moisture in the skin, leaving the complexion smooth, plump, and refreshed.

Instead of plain water, the formula uses sea buckthorn water (Hippophae Rhamnoides) to deliver additional vitamins and nutrients while supporting long-lasting hydration. The oil-free texture absorbs quickly, making it suitable for daily use without heaviness.

Key Benefits

Deep hydration
Sodium hyaluronate helps draw moisture into the skin and maintain long-lasting hydration.

Smooths skin texture
Hydration helps soften rough patches and improve overall skin smoothness.

Plumps fine lines
Moisture-rich ingredients help reduce the appearance of dehydration lines.

Soothes sensitive skin
Panthenol helps calm irritation and support the skin barrier.

Who It’s For

Ideal for anyone experiencing dryness, dehydration, dull skin, or rough texture. Suitable for all skin types, including sensitive skin.

How To Use

After cleansing and toning, apply a small amount to the face. Gently pat into the skin until fully absorbed, then follow with moisturizer.

Pro Tip

Apply the serum to slightly damp skin to help hyaluronic acid attract and retain more moisture for a plumper, dewy finish.
