COSRX The Hyaluronic Acid 3 Serum is a light, hydrating formula made to bring long-lasting moisture to your skin. It blends three kinds of hyaluronic acid, each with a different size, so that hydration reaches deep into your skin and also protects the surface. This helps your face feel soft, smooth, and refreshed throughout the day.

If you often struggle with dryness or tightness, this serum gives your skin exactly what it needs. The thin, water-like texture feels comfortable and sinks in fast, making it easy to add to your morning or evening skincare steps. It does not leave any heavy or greasy layer, so your skin feels clean and breathable after applying it.

This product is gentle and safe for daily use. It contains no added fragrance, artificial colors, or harsh ingredients. That means it works well even if your skin is sensitive or prone to breakouts. It keeps your skin barrier strong and adds the hydration needed to support a calm, healthy-looking appearance.

With daily use, your skin feels smoother and looks more radiant, even in dry weather or after washing your face.
