The COSRX The Hyaluronic Acid 3 Serum is a deeply hydrating formula that helps restore softness and bounce to your skin. Designed with a triple blend of low, medium, and high molecular weight hyaluronic acid, it delivers multi-layered moisture — replenishing hydration from within while keeping the surface smooth and refreshed. This serum leaves your skin feeling dewy, plump, and perfectly balanced.
Its silky, lightweight texture absorbs quickly without any stickiness, making it ideal for all skin types — from dry and sensitive to oily or combination skin. Enriched with ceramides, glycerin, and betaine, it helps reinforce the skin’s natural moisture barrier while maintaining long-lasting hydration. Midway through your skincare ritual, adding this serum will make your next products absorb more efficiently, helping your skin feel comforted and hydrated throughout the day.
This glow-giving serum layers beautifully with the COSRX Refresh AHA BHA Vitamin C Daily Cream Meandskin, creating the perfect combo for a luminous, supple complexion.
