Consisting of two completely different procedures, extraction of fat called liposuction and transfer of fat through injections. Both the donor and recipient sites are sedated by giving local anesthesia. After this, fat is harvested through injections from the sites where adipocytes are tightly packed, such as the buttocks or abdomen. However, the fat present in lateral sides of the thighs and lower abdomen is also good fat as it contains a larger concentration of adipose-derived stem cells. These stem cells promote angiogenesis and adipogenesis at the recipient site - multiple injections are used to do this. The material extracted is centrifuged, sedimented and filtered for excessive liquid and pure fat cells are injected just below the skin. This is the most difficult step of fat transfer to inject fat evenly in different layers of recipient tissue. Cannulas and syringes of different sizes are used to do this. In the case of breast augmentation, multiple fat injections are applied to the breasts. It is ensured that these fat cells are injected near a blood vessel so the cells don't die due to a lack of nutrition. Proper nutrition is needed for the cells to survive and grow.
