What is Hyaluronic Acid Hyaluronic Acid100% Pure Hyaluronic Acid is naturally found in skin. It is abundant in youthful skin and is the key compound that keeps our skin youthful and hydrated. It keeps the skin firm, moist, supple and smooth, and prevents wrinkles and fine lines by plumping the skin.
