Delivering triple-action hydration with three types of Hyaluronic Acid, this concentrated serum from COSRX targets moisture at multiple skin depths simultaneously for a visibly plumper, dewier, and more supple complexion. The Hyaluronic Acid 3 Serum combines low, medium, and high molecular weight HA to hydrate the surface, mid-layer, and deeper skin layers for comprehensive, long-lasting moisture that goes beyond what a single HA can achieve.

Key Benefits

• Triple Hyaluronic Acid Complex: Three molecular weights of Hyaluronic Acid penetrate different skin depths simultaneously for comprehensive surface-to-deep hydration and a visibly plumper complexion
• Deep & Long-Lasting Moisture: Multi-layer hydration locks moisture into the skin for a sustained dewy, supple skin feel that lasts throughout the day
• Fine Line Plumping: Intensive hydration visibly plumps and smooths dehydration-induced fine lines for a more youthful, bouncy complexion
• Skin Barrier Support: High-weight HA forms a protective moisture-locking layer on the skin surface to prevent transepidermal water loss and strengthen the skin barrier
• Lightweight & Fast-Absorbing: Serum texture absorbs instantly without stickiness, suitable for all skin types including oily and combination skin

Best For

Dehydrated, dry, and all skin types seeking intensive multi-layer hydration and fine line plumping. Ideal as a daily hydrating serum step.

How To Use

After cleansing and toning, apply a few drops to the face and neck. Gently press into skin until absorbed. Follow with moisturizer to seal in hydration. Use morning and evening for best results.
