As we age, our faces begin to show the effects of gravity, sun exposure and years of facial muscle movement, such as smiling, chewing and squinting. The underlying tissues that keep our skin looking youthful and plumped up begin to break down.
Injectable fillers procedure
Soft-tissue fillers, most commonly injectable collagen or fat,can help fill in these lines and creases, temporarily restoring a smoother, more youthful-looking appearance. When injected beneath the skin, these fillers plump up creased and sunken areas of the face. They can also add fullness to the lips and cheeks. Injectable fillers may be used alone or in conjunction with a resurfacing procedure, such as a laser treatment, or a recontouring procedure, such as a face-lift. Injected collagen and fat are primarily used to improve the appearance of the skin’s texture. They can help fill out deep facial wrinkles, creases and furrows, “sunken” cheeks, skin depressions and some types of scars. They can also be used to add a fuller, more sensuous look to the lips. Injectables are usually not sufficient for severe surface wrinkles on the face, such as multiple vertical “lipstick lines” that sometimes form around the mouth. Instead, your plastic surgeon may suggest a resurfacing technique, such as chemical peel, dermabrasion or laser treatments. Rather than filling in facial lines, resurfacing methods strip away the outer layers of the skin to produce a smoother appearance. Deep folds in the face or brow caused by overactive muscles or by loose skin may be more effectively treated with cosmetic surgery, such as a face-lift or brow-lift. Injectables are sometimes used in conjunction with facial surgery procedures; however, injectables alone cannot change facial contour the way surgery can.Types of fillers
Collagen
Collagen is used primarily to fill wrinkles, lines and scars on the face and sometimes the neck, back and chest. Collagen is a naturally occurring protein that provides support to various parts of the human body: the skin, the joints, the bones and the ligaments. Injectable collagen, patented by the Collagen Corporation under the trade names Zyderm and Zyplast, is derived from purified bovine collagen. The purification process creates a product similar to human collagen. Injectable collagen received approval from the Food and Drug Administration in1981. It is produced in various thicknesses to meet individual patient needs.Fat
In the medical world, the fat-injection procedure is known as autologous fat transplantation or microlipoinjection. It involves extracting fat cells from the patient’s abdomen, thighs, buttocks or elsewhere and reinjecting them beneath the facial skin. Fat is most often used to fill in “sunken” cheeks or laugh lines between the nose and mouth, to correct skin depressions or indentations, to minimize forehead wrinkles and to enhance the lips.Anesthesia
Because the anesthetic agent lidocaine is mixed in with collagen, additional anesthetic is usually not used. However, if you are especially sensitive to pain, your doctor may use a topical cream anesthetic or a freon spray to numb the injected area. Or, you may elect to have an injected local anesthetic or sedative drugs. Both the donor and recipient sites of fat are numbed with local anesthesia. Sedation can be used as well. If you elect to use sedation, be sure to arrange for a ride home after your treatment.The surgery
The injectable filling procedures take from 15 min to 1 hour. Collagen Treatment with collagen can begin after a skin test determines that you’re not allergic to the subsstance. The collagen is injected using a fine needle inserted at several points along the edge of the treatment site. If a local anesthesia has not been used, you may feel some minor stinging or burning as the injections are administered. Since part of the substance is salt water that will be absorbed by the body within a few days, your doctor will slightly overfill the area.You may be asked to hold a hand mirror during the procedure to help your doctor decide when you’ve had enough.
Fat After both the donor and recipient sites are cleansed and treated with a local anesthesia, the fat is withdrawn using a syringe with a large-bore needle or a cannula (the same instrument used in liposuction) attached to a suction device. The fat is then prepared and injected into the recipient site with a needle. Sometimes an adhesive bandage is applied over the injection site. As with collagen, “overfilling” is necessary to allow for fat absorption in the weeks following treatment. When fat is used to fill sunken cheeks or to correct areas on the face other than lines, this overcorrection of newly injected fat may temporarily make the face appear abnormally puffed out or swollen.
