Autologous fat is a person's own fatty tissue, collected for transfer to another part of the body. After liposuction, it is processed and used, for example, to change volume or contour. The procedure is also known as lipofilling.
Some of the transferred fat cells may survive long term, while others are reabsorbed. The proportion cannot be predicted precisely. The result depends on harvesting, processing, the recipient site and the person's tissue characteristics.
Using the body's own material does not mean treatment is risk-free. Infection, fat necrosis, cysts, calcification and irregular contours are possible. Depending on the body area, serious vascular complications may also occur. Suitability is therefore assessed separately for each procedure.
