Fat grafting combines liposuction and injecting adipose or fat cells to different areas of the body. Liposuction uses a cannula or suction device to remove fat from underneath the skin. This fat is then processed in an external system and prepared for injection into regions that need volume. Fat grafting allows for smoothing of areas around the body and an ability to shape a natural look and feel. Autologous fat, or fat from your own body, replaces like with like and avoids the need to use synthetic rejuvenation.
