Hyaluronic acid(HA) has amazing moisturizing properties; it is able to hold 1,000 times its weight in water, supporting the appearance of the skin. Because it holds water, HA is a lubricating compound and a natural cushioning barrier in joints. Hyaluronic acid may also bind to cellular receptors located on the surface membrane of cartilage, where it seems to support the immune response in the tissues and support healthy cartilage.
