Soft-tissue fillers, most commonly injectable collagen or fat, can help fill in these lines and creases, temporarily resorting a smoother, more youthful looking appearance. When injected beneath the skin, these fillers plump up creased and sunken areas of the face.
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.
After the patient is treated with a local anesthesia, the fat is withdrawn using a syringe with a large-bore needle or a Cannula attached to a suction device. The fat is then prepared and injected into the desired site with a needle. Sometimes an adhesive bandage is applied over the injection site.
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 injection fullness disappears within 3-6 months. Therefore, repeated injections may be necessary.
