Cosmetic surgery using Restylane filler rejuvenates a patient's face through a series of injections into the skin. A natural filler, Restylane is safer than many other fillers floating around the market which can cause severe allergic reactions.

Restylane augments the lips, diminishes facial wrinkles, contours the mouth and cheeks, and reduces lines around the mouth, eyes and nose. Restylane, a clear gel that is injected right under the skin, adds natural-looking volume to the area being treated. It smoothes out wrinkles, folds and lines, making them appear less prominent.

Over time, the Restylane gel dissolves but doesn't leave behind any traces or residue. Restylane usually lasts about six months, and results are immediate after the procedure is done. But sometimes you may need additional Restylane injections to reach your desired goal.

If you are seriously considering Restylane procedures, you must make an appointment with a qualified plastic surgeon. You must be eighteen or older to be a candidate and must fully understand the pros and cons of the procedure.

A local or a topical anesthetic will be used to numb the site of the injections. You will experience moderate tingling, burning or stinging sensations at the injection sites, which is normal. After the injections, you may experience swelling and redness around the injection sites. This may last from several hours to several days. The lips may also swell and appear asymmetrical in shape. These effects usually last a few weeks and then subside. Sometimes, very small lumps may be found around the injection sites. Normally, these aren't noticeable but can last for several months after the injections.

Restylane's main advantages include the following: no testing is necessary ahead of time because this gel contains no animal products; the effects last the same amount of time as collagen fillers; Restylane is biodegradable; it has a proven safety record; and though only temporary, the results of treatment with Restylane can last from six months to a year, depending on the patient.

The disadvantages include the following: In the United States, you may be unable to find a physician who is experienced with Restylane. Because no anesthetic is given, the injections may be uncomfortable, although in most cases a topical numbing agent is used. Other drawbacks include the fact that injections may need to be redone in as little as four months (however, some results last about a year) to maintain the desired appearance. Pain and the swelling associated with the procedure are also possible.
