Autologous fat transfer: Fat is taken from another site on your own body and prepared for injection into your skin. The fat is injected beneath the surface of the skin to elevate depressed scars. This method of autologous (from your own body) fat transfer is usually used to correct deep contour defects caused by scarring from nodulocystic acne. Because the fat is reabsorbed into the skin over a period of 6 to 18 months, the procedure usually must be repeated. Longer lasting results may be achieved with multiple fat-transfer procedures.
