COSRX The Hyaluronic Acid 3 Serum

COSRX The Hyaluronic Acid 3 Serum

Experience the next evolution of hydration with COSRX The Hyaluronic Acid 3 Serum — a cutting-edge, triple Hyaluronic Acid serum that delivers deep, multi-dimensional moisture at three different skin levels for unparalleled plumping, smoothing, and long-lasting hydration that transforms even the most dehydrated skin.

Key Benefits

• Triple Hyaluronic Acid Complex: Combines three forms of Hyaluronic Acid — Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, and Sodium Acetylated Hyaluronate — each with a different molecular weight to penetrate the skin at different depths, delivering comprehensive hydration from the surface all the way to deeper skin layers.
• Instant & Long-Lasting Hydration: The multi-weight HA complex provides an immediate surge of surface moisture while simultaneously delivering deep, sustained hydration that keeps skin plump, dewy, and comfortable for hours.
• Visibly Plumps & Smooths: Hyaluronic Acid attracts and retains up to 1,000 times its weight in water, instantly plumping fine lines caused by dehydration and giving skin a visibly fuller, smoother, and more youthful appearance.
• Strengthens Skin Barrier: Sodium Acetylated Hyaluronate — a next-generation HA — forms a protective film on the skin's surface that locks in moisture, reduces transepidermal water loss (TEWL), and strengthens the skin barrier over time.
• Brightens & Revitalizes: Well-hydrated skin reflects light more evenly, giving skin a natural, healthy radiance and reducing the appearance of dullness and fatigue.
• Lightweight & Fast-Absorbing: A silky, water-based serum texture that absorbs instantly without any stickiness, heaviness, or residue — comfortable for all skin types and all climates.

How to Use

Apply to clean skin in the AM and/or PM after toning and before heavier serums or moisturizer. Dispense 2-3 drops onto clean fingertips and gently press and pat into the face and neck until fully absorbed. For best results, apply to slightly damp skin immediately after toning to maximize moisture absorption. Follow with moisturizer and SPF 30+ in the morning.

Tip: Layer generously for an intensive hydration boost, or mix a drop into your moisturizer for an extra surge of hydration on particularly dry days.
