The amount required depends on which parts of the body are to be filled with the patient’s own fat and to what extent. Depending on the original size, between 150 ml and 300 ml per side is required for a natural breast augmentation. In the face, 20 ml to 50 ml of fat is often enough to increase volume in the cheekbones or eye sockets. If you want to rejuvenate the backs of your hands, between 30 ml and 50 ml per hand are usually required.
