Aging often leads to a loss of volume in the face. This results in deepening facial lines, thinning lips and a sunken appearance of the face. Plastic surgeons have used different fillers to restore this volume. Fat injections are often used at time of facelift.
Although manufactured fillers such as Juvederm and Bellafill are easy to use, fat still has many advantages.
Fat may provide a permanent correction, is available in larger amounts and may have other benefits. Newer techniques have improved the amount of fat which permanently takes.
