THE TREATMENTS
Collagen
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 in 1981. It is produced in various thicknesses to meet individual patient needs.
Collagen is used primarily to fill wrinkles, lines and scars on the face and sometimes the neck, back and chest.
The procedure: Treatment with collagen can begin after a skin test determines that you're not allergic to the substance. The collagen is injected using a fine needle inserted at several points along the edge of the treatment site. If a local anesthetic 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.
After treatment: Immediately following treatment, you may notice some minor discomfort, stinging or throbbing in the injected area. Occasionally some bruising or swelling will occur, but it is usually minor. Any redness that appears in the injected site usually disappears within 24 hours. However, in some individuals, particularly fair skinned patients, this redness may persist for a week or more. Tiny scabs may also form over the needle-stick areas; these generally heal quickly.
No bandaging is needed and you are free to eat, drink, and wear makeup with sunblock protection shortly thereafter. There may be some temporary swelling and redness in the treated area which should dissipate within a few days. If these symptoms persist, contact your surgeon.
Result: As stated earlier, the duration of results from collagen injections is variable. Collagen's longevity depends on the patient's lifestyle and physical characteristics as well as the part of the body treated. In general, the injected material is likely to disappear faster in areas that are more affected by muscle movement.
Your doctor can help you determine how long you can go between treatments to best maintain your results.
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.
The procedure: 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 over correction of newly injected fat may temporarily make the face appear abnormally puffed out or swollen.
After treatment: If a larger area was treated, you may be advised to curtail your activity for a brief time. However, many patients are able to resume normal activity immediately. You can expect some swelling, bruising or redness in both the donor and recipient sites. The severity of these symptoms depends upon the size and location of the treated area. You should stay out of the sun until the redness and bruising subsides - usually about 48 hours. In the meantime, you may use makeup with sunblock protection to help conceal your condition.
The swelling and puffiness in the recipient site may last several weeks, especially if a large area was filled.
Results: The duration of the fat injections varies significantly from patient to patient. Though some patients have reported results lasting a year or more, the majority of patients find that at least half of the injected fullness disappears within 3 - 6 months. Therefore, repeated injections may be necessary. Your doctor will advise you on how to maintain your results with repeat treatments.
YOUR NEW LOOK
If you're like most patients, you'll be very satisfied with the results of your injectable treatments. You may be surprised at the pleasing results that can be gained from this procedure.

If you're considering injectables...
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.
