Hyaluronic acid *4

Its high water-retention capacity, capable of holding 6 liters of water with just 1 gram, provides widespread hydration to the skin's surface.
It is a moisturizing ingredient found in areas of the body that contain a lot of water, such as tears, skin, and cartilage, and is key to keeping things fresh and supple.
