The Hyaluronic Acid 3 Serum

COSRX Hyaluronic Acid 3 Serum

A lightweight yet deeply hydrating serum formulated with three types of Hyaluronic Acid to deliver multi-layer moisture and long-lasting hydration. Designed to replenish and lock in moisture, this advanced formula helps restore plumpness, smooth fine lines, and support a healthy, youthful-looking complexion.

Hyaluronic acid naturally exists in the skin to maintain hydration and elasticity. Over time, its levels decline, leading to dryness and visible signs of aging. This serum targets those concerns by delivering hydration to both the surface and deeper layers of the skin, improving suppleness and overall texture.

Infused with skin-replenishing ingredients like Ceramide NP and nourishing amino acids, it strengthens the skin barrier while maintaining a soft, dewy finish—without heaviness or stickiness.

Suitable for all skin types, including oily and acne-prone skin, this fast-absorbing formula leaves skin refreshed, smooth, and comfortably hydrated.

1. After cleansing and toning, apply a few drops during the serum step.
