High molecular weight hyaluronic acid makes it possible to enter the skin. It consists of molecules of 0.75 to 1.5 million Daltons. Its water-holding ability – specifically its natural capacity for holding water that is 1000 times its weight – makes it an exceptional hydrating agent and thus a popular ingredient in the cosmetic industry; this constituent is widely used in rejuvenating moisturizing products intended to address the appearance of wrinkles.
Sodium Hyaluronate (Hyaluronic Acid) Low Molecular Weight (HMW) will not form a viscous gel in water. But they can penetrate the skin much easier and have actually a better nourishing and regenerating effect once absorbed by skin.
