The COSRX Hyaluronic Acid 3% Serum delivers a targeted, concentrated hit of hyaluronic acid to instantly plump, hydrate, and soften skin. At 3% concentration, it works deep within the skin's layers to attract and lock in moisture — giving skin a visibly plumper, dewier appearance after just one use.
Lightweight, layerable, and essential for anyone dealing with dehydration, fine lines, or tight, uncomfortable skin.
✅ All skin types — especially dehydrated, dry, and mature skin. Ideal for anyone experiencing tightness, dullness, or visible fine lines caused by lack of moisture. Perfect in cold, dry climates.
20ml
Refer to the product packaging for the complete and most current ingredient list. The manufacturer may update the formula without notice.
After cleansing and toning, apply 2–3 drops onto fingertips and press gently into slightly damp skin. Follow immediately with moisturizer to seal in the hydration. Use morning and/or evening.
When to Use
Morning and evening. Apply to damp skin for maximum absorption — the hyaluronic acid attracts moisture from the surrounding environment, so a slightly damp application maximizes its effect.
