With technical improvements over the last 10 years, the quality and longevity of fat has made it the filler of choice for many patients. Whereas Restylane may last 3-6 months and Juvederm 6-8 months, the patient’s own fat has much greater durability.
Although some of the fat will remain as a permanent result, the average length of time between injections is 3-5 years. The fat is harvested, usually from the abdomen, sometimes from the flank or thigh, and then put in a sterile centrifuge to concentrate the fat cells. It is then placed with a series of passes in to the target areas, typically the nasolabial folds, lips, and prejowl area. As there is a little swelling and bruising, it is advisable for the patient to take a week off work.
