Hyaluronic acids are naturally occurring chemical compounds produced by your body. The Food and Drug Administration has approved various forms of hyaluronic acid for various medical purposes. Manufacturers also market hyaluronic acid for skin care. Further clinical research is needed, however, to confirm the cosmetic benefits of hyaluronic acid. You should speak with a medical professional before using this compound.
Function in the Body
Hyaluronic acids occur in your body's joints, especially your knees. However, your body also produces hyaluronic acids in several other places, for example, the eyes, cartilage and other tissues. According to "Nelson Textbook of Pediatrics," your body uses hyaluronic acids as both a lubricant and shock absorber. Further, "Harrison's Principles of Internal Medicine" states that individuals suffering from arthritis can use hyaluronic acid supplements to provide protection for joints. Manufacturers offer both injectable and oral forms of hyaluronic acid supplementation. However, doctors typically recommend the injectable form.
Physical Properties
Hyaluronic acid has a viscous consistency, allowing it to work well as a connective lubricant positioned between bones. Before medical scientists understood the makeup of the acids and the role the acids play in the body, hyaluronic aid was commonly referenced as "goo." Hyaluronic acid also contributes to the consistency of your cartilage by protecting the coating of your cartilage cells. Hyaluronic acid contributes to your cartilage's resistance against pressure from the outside.
History of Approval
Though not fully understood until the mid-twentieth century, hyaluronic acids have now received approval from both the Federal Drug Administration and the European Medicines Agency. The Food and Drug Administration has approved forms of hyaluronic acid for a myriad of medical applications including the treatment of osteoarthritis and eczema, healing after cataract surgery, locating tumors in prostate cancer and breast cancer, and general wound-healing.
Other Uses
Compounds manufactured from hyaluronic acid are also used in cosmetics. You can find hyaluronic acids in many skin care products. These skin care products purportedly promote a healthy complexion and fight aging. Additionally, manufacturers recommend hyaluronic acids to temporarily smooth wrinkles in your skin and add fullness to your skin. Internally, manufacturers recommend hyaluronic acid to promote the process of skin renewal by facilitating the healthy functioning of collagen.
