Hyaluronic acid (HA; conjugate base hyaluronate), also called hyaluronan, 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.
Hyaluronic acid is a common ingredient in skin-care products. It is used as a dermal filler in cosmetic surgery. Some people apply hyaluronic acid to the skin for healing wounds, burns, skin ulcers, and as a moisturizer.
