COSRX The Hyaluronic Acid 3 Serum

Deeply hydrate and replenish your skin with COSRX Hyaluronic Acid 3 Serum, a lightweight Korean hydrating serum formulated with 3% Hyaluronic Acid to help boost moisture levels, improve skin softness, and support a healthy-looking complexion. Designed to deliver intense hydration without heaviness, this moisture-boosting serum helps keep skin smooth, plump, and balanced throughout the day.

The fast-absorbing, non-greasy texture layers comfortably into both simple and advanced skincare routines, leaving skin refreshed, supple, and comforted.
