Rather than using silicone or a temporary filler, a plastic surgeon can use your own fat for permanent lip augmentation. The procedure is similar to body contouring (link), where fat is removed from different places on your body like the belly, back and thighs. Once the fat is removed, it’s refined and then injected into your lips in various places to create the lips you want. The fat can also be injected into facial wrinkles and other place on your face to rejuvenate the skin and produce a more youthful and natural appearance.
