Facial aging is classically thought to involve the sagging of skin, related to the cumulative effects of gravity. One of the major signs of aging is the loss of volume in various facial areas, leading to hollowness.
One of the major uses of in-office facial fillers, like Juvéderm and Restylane, is to restore this volume to targeted facial areas.
A permanent solution is the use of fat, transferred from other areas of the body like the belly or the legs. When transferred to the face, this fat can replace the lost volume, resulting in a more youthful appearance.
Facial fat transfer is commonly done in conjunction with other facial procedures, like facelift, necklift, and liposuction.
