Hyaluronic acid therapy is a technique used in cosmetic surgery for the purpose of facial augmentation. The therapy is administered through a needle or a hyaluronic acid injection. These are dermal fillers used to add volume to deflated or depressed areas in the skin. The purpose is to improve the facial contour and reduce the depressions caused by scars, injury, illness or aging.

What is Hyaluronic Acid?

Hyaluronic acid is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial and neural tissues. This substance is very well tolerated for cosmetic purposes as it is normally found in every living organism. An average person, weighing approximately 70 kg (154 lbs), has roughly 15 grams of hyaluronan in the body. This common ingredient in skin-care products was approved in by the FDA in 2003, for filling soft tissue defects such as facial wrinkles. The injection is also used to relieve rheumatism and other kinds of joint pain. Hyaluronic acid can be described as a gel like substance situated between the skin and connective tissues supporting the skin. Injected hyaluronic acid acts like a pillow that supports the facial structures that have lost their volume and elasticity. The acid also hydrates the skin, bringing water to the surface and providing characteristic youthful appearance.

What is it used for?

Hyaluronic acid fillers are use for cosmetic purposes and various facelift procedures. These injections can correct frown lines between the eyebrows, vertical lines above the upper lip, marionette lines that run from the nose to the corners of the mouth, worry lines across the forehead, crow’s feet at the corner of the eyes and skin depressions in the jaw or cheeks. They can also be used for redefinition of the border of the lip by eliminating lip feathering, and for different scars such as those caused by burns, acne, or wounds.

The correction is only temporary and can last somewhere between three and five months. Many different factors determine the duration of filling. Some of these factors include patient’s lifestyle, body chemistry and the natural rate of aging.

The procedure

The procedure is non-invasive and uses only topical anesthetic. It is completely painless as the anesthetic diminishes any pain caused by the needle penetration. Doctors will use special extra-thin needles and the treatment usually lasts between fifteen minutes and an hour. To get the maximum benefits of hyaluronic acid injections, one should have new procedures two to three times a year. In most of the cases, patients will need a couple of extra visits to the doctor’s office before they reach the targeted results. It all depends on how the body reacts to the hyaluron.
