Cosrx's advanced hydration serum harnesses three molecular weights of hyaluronic acid to penetrate multiple skin layers, delivering intense moisture from within. This lightweight formula absorbs quickly without residue, plumping fine lines and restoring elasticity. Ideal for dehydrated or compromised skin barriers, it layers seamlessly under moisturizers and treatments. The 20ml size offers concentrated hydration that extends across weeks of consistent use, making it an essential step in any skincare regimen focused on deep, lasting moisture retention.
