Dr. Vanek writes about Innovations in Body Contouring 
Lipoaspiration combined with lipoinjection is probably the best surgical option for the correction of contour defects of the extremities, augmentation of the buttocks, and rejuvenation of the face. The basis for success in fat transfer is the use of harvested stem cells. Cells from the fluid removed after VASER liposuction have been shown to be viable and readily transferable. Since VASER lipo is a gentle technique and highly selective, the tissue aspirated is primarily fat cells that have been disjoined from their tissue matrix selectively by the VASER ultrasound. Transfer to areas of body contour deficiency is likely to be successful in healthy people. Fat transfer to the breast is slowly achieving acceptance in other parts of the world, but I don’t recommend it yet. Combining fat transfer with facial rejuvenation yields beautiful, youthful restoration of appearance. The local growth factors in the fat transfer actually thicken the dermis while the face surgery restores volume and contours. Volume improvement seen by 3 months post op will likely persist for many years.
PS Fat transfer to the lips and face can be done with sedation and local anesthesia. The tummy is the most common donor site!
