HA also supports the formation and maintenance of collagen, an important connective tissue. Collagen degradation is believed to cause a decrease in skin tone and elasticity.

There are also several new, non-invasive beauty products that contain Hylauronic acid or work to stimulate the body's own Hyaluronic acid production. Apparently full lips a la Angelina Jolie are a must-have because celebrities of all ages are going gaga for City Lips, a cutting edge product developed by City Lips Cosmetics. The City Lips product stimulates lips to produce their own collagen and Hyaluronic acid, painlessly increasing the size of lips.

Hyaluronic acid, also known as HA, naturally plays an important role in tissue hydration and lubrication. Simply put, the protein compound takes years off skin, helping to make it moist, vibrant and supple. HA's name derives from "hyalos" ? the Greek word for glass, which accurately describes its transparent, glassy molecular appearance.

Hyaluronic acid naturally occurs in human skin and is capable of holding 1000 times its own weight of water. Although the amount of HA in skin decreases with age, supplementing the body's natural supply can help offset visible signs of aging. The protein acts like an ?instant facelift,? retaining essential moisture in the skin layers to reduces wrinkles caused by dehydration and aging.

Hyaluronic acid injections can last for as long as 6-12 months while collagen only lasts for about 3-4 months. Thus, between increased safety, effectiveness and results, it appears as if Hyaluronic acid is poised to become the wrinkle filler, lip plumper and fine line killer of choice in today's highly competitive cosmetic surgery market.

The hyaluronic acid product Restylane is the first and only dermal filler made of crystal-clear gel called NASHA (Non-Animal Stabilized Hyaluronic Acid). Restylane uses a dual mechanism of action to correct wrinkles and folds. Upon being injected beneath the skin's surface, the NASHA gel adds natural volume and lift to smooth wrinkles and folds.

Hyaluronic acid is a natural substance that keeps skin looking firm. When a person develops fine lines and wrinkles, this is a sign of Hylauronic acid depletion in the skin. Perlane is a dermal injection of Hyaluronic acid which fills in wrinkles and lines, thereby giving the skin back some of that youthful appearance. There are other hyaluronic acid treatments currently available and many of them are administered to the skin via injection by a cosmetic surgeon or cosmetic dermatologist.

Hyaluronic Acid (HA) is naturally occurring in our bodies and acts to enable elasticity and moisture retention, which in turn promotes healthy skin cell development. It has become a key active ingredient in operative skin care products. It is most naturally and commonly found and concentrated in connective tissues especially skin where it has a protective, structure stabilizing and shock-absorbing role.

A chemical response or reaction of enzymes cause the hyaluronic acid to break down. When this happens the skin reacts. The reaction is sagging skin, wrinkles and puffy eyes. So to firm sagging skin the enzymatic action that makes hyaluronic acid lose its power must be stopped.
