Hyaluronic acid is a type of polysaccharide called a glycosaminoglycan. Also known as hyaluronan or hyaluronate, it occurs naturally in the human body and is central to regulating cell growth and renewal. In fact, it is found extensively in connective, epithelial, and neural cells. As such, hyaluronic acid has found its way into many skin care products, particularly anti-wrinkle formulations. In addition, it has been credited with extending life in those who consume high amounts in the diet, resulting in the media dubbing it as the "fountain of youth."

Hyaluronic acid is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints. The hyaluronic acid that is used as medicine is extracted from rooster combs or made by bacteria in the laboratory.
People take hyaluronic acid for various joint disorders, including osteoarthritis. It can be taken by mouth or injected into the affected joint by a healthcare professional.
The FDA has approved the use of hyaluronic acid during certain eye surgeries including cataract removal, corneal transplantation, and repair of a detached retina and other eye injuries. It is injected into the eye during the procedure to help replace natural fluids.
Hyaluronic acid is also used as a lip filler in plastic surgery.
Some people apply hyaluronic acid to the skin for healing wounds, burns, skin ulcers, and as a moisturizer.
There is also a lot of interest in using hyaluronic acid to prevent the effects of aging. In fact, hyaluronic acid has been promoted as a "fountain of youth." However, there is no evidence to support the claim that taking it by mouth or applying it to the skin can prevent changes associated with aging.
