What Is Hyaluronic Acid And How to Use it?
Hyaluronic acid is a natural polysaccharide, a transparent, sticky colloidal substance that is filled in the space of cells and collagen fibers in the human body and is covered in some connective tissue. Hyaluronic acid not only maintains the elastic function of the skin but also locks a large number of water molecules. It has a moisturizing and lubricating function on the tissue and is also a component of the ocular lens and joint lubricating fluid. So it is often used to make beauty cosmetics and drugs for arthritis and cataracts.
