The COSRX Hydrium Triple Hyaluronic Moisture Ampoule is a viscous, hydrating serum designed to leave dry or dehydrated skin feeling supple and moisturized. It contains Vitamin B5 (d-panthenol) for hydration and anti-inflammatory benefits, and hyaluronic acid to lock in moisture and re-plump the skin. This formula is vegan, hypoallergenic, dermatologist tested, and free from parabens, sulfates, and phthalates. Its concentrated active ingredients provide a more pronounced and faster effect than a face cream, with a liquid consistency that ensures easy application and absorption. The serum effectively hydrates and nourishes, restores skin elasticity, protects against external damage, and promotes a fresh, youthful appearance. To use, gently pat an appropriate amount into clean skin with fingertips. It can be layered under day or night cream, or used on its own.
