Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from the vitreous body of the bovine eye. Most importantly, it has a special water-retaining effect, and it is the substance with the best moisturizing property found in nature, which is called an ideal natural moisturizing factor.

Sodium hyaluronate is a water-soluble salt derived from hyaluronic acid, which is naturally produced by our body. Like hyaluronic acid, the weight of sodium hyaluronate in water can reach 1000 times its own weight, but this form can penetrate deep into the skin and is more stable in beauty product formulations (meaning it can last longer time).
