Liposuction is a cosmetic procedure that involves removing excess fat from specific areas of the body, such as the abdomen, hips, thighs, or arms, to improve their shape and appearance. The procedure is performed using a thin, hollow tube called a cannula, which is inserted through small incisions in the skin and used to suction out the fat. Liposuction can be performed on its own or in combination with other cosmetic procedures to achieve a more comprehensive result.
