How long will the results last?
Survival of the fat cells depends on the gentleness of their harvesting, processing and injection as well as the injection technique. Injection of small volumes in multiple tracts into the recipient bed improves longevity by promoting vascularization of the grafted fat which needs blood vessel nourishment to survive. PRP, if used, also stimulates vascularization of the newly transplanted fat cells. The transplanted fat cells have the potential to last many years.
Fat injection treatment may need to be repeated if the volume is not sufficient. In the breast more than one injection (lipo augmentation) may be necessary to balance the size of the breasts. Survival of grafted fat tends to be greater in areas of less movement such as cheeks, breasts or back of the hands than in the lips and mouth which may need touch-up treatment if the fat is resorbed.
