Hyaluronic acid exists in all living organisms. It is responsible for lubrication in the vitreous humor in the eye, in skin and in the joints. You can use hyaluronic acid for various purposes. For example, you can use it as a way to treat signs of aging, to lubricate your eyes or as a way to soothe viral infections of the eyes. It is derived from rooster combs, a flap of skin on a rooster’s head, and is chemically synthesized.

If you have ever suffered from dry eyes, you may have already used hyaluronic acid. Found naturally in the vitreous fluid of the eyes, hyaluronic acid is used in artificial tears as a lubricant to help relieve the symptoms of dry eyes. It can retain almost 100 times its weight in water and is used in ophthalmic surgery to protect sensitive eye tissues, according to an article in the February 2, 1992 issue of the "New York Times."
Hyaluronic acid is as used as wrinkle filler for lines around the eyes. It is injected directly into wrinkles around the eye area, such as crow’s feet. Manufactured hyaluronic acid acts the same as natural hyaluronic acid and gradually breaks down and is absorbed by the body in 3 to 9 months from the initial injection, according to the New Zealand Dermatological Society
You can find hyaluronic acid in many wrinkle creams for the eye area as an anti-aging ingredient. Hyaluronic acid is naturally abundant in your skin and part of all connective tissues. It attracts and retains water and moisture to your skin. It has no known side effects and has such low incidence of allergic reactions that testing is not required, according to a study published in the March 2006 "Dovepress Clinical Interventions in Aging." These eye creams come in both natural and manufactured formulations of hyaluronic acid.
Conjunctivitis, also referred to as pinkeye, is an inflammation that is on the inside of the eyelid. It can be caused by viruses, bacteria, allergies, chemicals and irritation from contact lenses. It is very contagious; you can contract it simply by touching someone who is infected and then touching your eye. Treatment with an eyewash solution containing ginkgo biloba extract with hyaluronic acid showed a significant decrease in symptoms when used for one month, notes the University of Maryland Medical Center.
