Vaser Liposuction is first performed at the donor sites to harvest fat that will later be transferred. Small incisions are made in inconspicuous areas, like the belly, flanks, lower back, or inner thighs. Dr. Sanchez-Navarro injects a tumescent solution into the target sites to loosen and remove fat. Then, the surgeon uses a suction cannula (thin tube) attached to a vacuum device to remove excess fat deposits through the incisions.
