Cosrx The Hyaluronic Acid 3 Serum is formulated with 3% customized hyaluronic acid to deliver deep and lasting hydration for all skin types. As an essential skincare ingredient, hyaluronic acid quickly absorbs into the skin to restore moisture, improve elasticity, and maintain a healthy skin barrier. This serum is especially beneficial for dry and dehydrated skin, helping to relieve flakiness, prevent makeup clumping, and boost overall moisture retention. It effectively targets dehydration, dryness, rough texture, and sensitivity, leaving the skin feeling soft, smooth, and revitalized. With its lightweight, non-greasy texture, it absorbs easily to provide a fresh, hydrated finish and a supple complexion.
