This ampoule contains 100% pure sodium hyaluronate, a stable, water-soluble form of hyaluronic acid that has smaller molecules than hyaluronic acid, to better penetrate the skin and pump it with hydration. Just a few drops help plump and hydrate skin, making it appear smoother and firmer over time. This powerful booster infuses skin with intense moisture without using harsh ingredients or potential irritants like parabens, artificial fragrance, silicones, surfactants, and mineral oil. How to use: Apply twice daily to enitre face and neck. Use it alone or mix with other products like your moisturizer to amp up the effects.
