COSRX The Hyaluronic Acid 3 Serum is an intensive hydrating serum designed to deliver long-lasting moisture to dry, dehydrated, and moisture-starved skin. Powered by 3% pure Hyaluronic Acid, this lightweight formula works like a moisture reservoir, attracting and retaining hydration within the skin to help restore softness, suppleness, and comfort. Unlike heavy moisturizers that can feel greasy, this fast-absorbing serum penetrates quickly into the skin, providing deep hydration without clogging pores or leaving a sticky residue. It helps relieve tightness, dryness, rough texture, and dullness while promoting a naturally healthy, dewy complexion.

To maximize hydration and barrier support, COSRX combines Hyaluronic Acid with Ceramides and Natural Moisturizing Factors (NMF). This powerful combination not only replenishes moisture but also strengthens the skin’s protective barrier to prevent moisture loss throughout the day. As skin becomes better hydrated, it appears visibly plumper, smoother, and more radiant. Fine dehydration lines look softened, makeup applies more evenly, and the complexion feels comfortable and refreshed. Suitable for all skin types, especially dry, dehydrated, and sensitive skin, this serum provides daily hydration support for healthier and more resilient skin.

Advanced Moisture Barrier Support & Skin Comfort

Healthy skin depends on a strong moisture barrier, and COSRX The Hyaluronic Acid 3 Serum is formulated specifically to support that function. Hyaluronic Acid attracts water to the skin, while Ceramides help seal moisture into the skin’s surface and protect against external stressors. Natural Moisturizing Factors work alongside these ingredients to mimic the skin’s own hydration system, helping maintain optimal moisture levels throughout the day. Together, these ingredients help reduce dryness, improve skin elasticity, and restore a smoother, healthier-looking appearance.

The lightweight texture makes this serum easy to incorporate into any skincare routine. Whether used alone or layered with other skincare products, it absorbs effortlessly and provides immediate hydration without heaviness. With continued use, the skin feels more balanced, hydrated, and resilient against environmental factors that contribute to moisture loss. It is particularly beneficial for individuals experiencing seasonal dryness, dehydration from air conditioning, makeup clumping, or skin that feels tight and uncomfortable after cleansing.
