Natural hydrating agent†
Hyaluronic acid is a natural lubricating component of skin tissue, joint fluid, eye fluid, and other connective tissues throughout the body. Hyaluronic acid belongs to a subset of polysaccharides called glycosaminoglycans which are moisturizing and hydrating agents in the body.† Water readily binds to hyaluronic acid, forming a jelly-like substance that fills the spaces between collagen and elastin. This hydrates the skin by holding in water. It also acts as a cushioning and lubricating agent in synovial fluid surrounding joints, thus protecting against mechanical friction.†
As part of the vitreous humor of the eye, hyaluronic acid provides needed lubrication to prevent eyes from becoming dry. Aging, along with exposure to environmental factors such as pollutants and sunlight that generate free radical molecules can degrade and deplete the body’s natural reserve of hyaluronic acid.
