What is Hyaluronic Acid for?

Hyaluronic Acid, sometimes known as hyaluronan, is naturally produced by your body. It is found in the highest concentrations in fluids of the eyes and joints, as well as under the skin. Hyaluronic Acid can retain water to keep tissues well lubricated and moist. It also helps to reduce friction in moving joints.

Commercially, Hyaluronic Acid is used by people to relieve dry eyes and dry skin. It is a common ingredient in many cosmetic and skincare products. Eating foods high in vitamin C and amino acids, such as oranges, kale, broccoli, spinach, and lettuce, helps our bodies produce more hyaluronic acid.

Medically, Hyaluronic Acid is available in its salt form, Sodium Hyaluronate. It is approved as an injection for cataracts, lens implantation, and various joint disorders, including osteoarthritis of the knee. It is also used in active wound dressings, which promotes the recovery of skin ulcers and wounds.
