Planning your procedureCollagen
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.
Collagen is used primarily to fill wrinkles, lines and scars on the face and sometimes the neck, back and chest
Preparing for your procedureFacial rejuvenation is very individualized. That's why it's important to discuss your hopes and expectations with a board-certified plastic surgeon who has experience with many different types of surgical and non-surgical facial procedures.
In your initial consultation, your plastic surgeon will evaluate your face - the skin, the muscles and the underlying bone - and discuss your goals for the surgery. Your doctor will help you select a treatment option based on your goals and concerns, your anatomy and your lifestyle.
Your surgeon will ask you about your medical history, drug allergies, and check for conditions that could cause problems, such as active skin infections or non-healed sores from injuries. Collagen injections are generally off limits for pregnant women, individuals who are allergic to beef or bovine products, patients who suffer from autoimmune diseases, and those who are allergic to lidocaine (the anesthetic agent contained in the syringe with the collagen material). For more specific information about the contraindications and risks of collagen use, ask your doctor for the manufacturer's brochure for patients.
Insurance usually doesn't cover cosmetic procedures. However, if your injectable treatment is being performed to treat a scar or indentation from an accident or injury, you may be reimbursed for a portion of the cost. Check with your insurance carrier to be sure.
Where your treatment will be performed
Injectables are usually administered in a surgeon's office-based facility. If, however, you are being hospitalized for a facelift, neck lift, brow lift, or any other procedure, your injections may be administered in the hospital as well.
Types of anesthesia
Collagen: 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.
Step OneThe 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 anesthesia has not been used, you may feel some minor stinging or burning as the injections are administered.
Step TwoSince 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 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.
