Results can vary, depending upon several factors such as what area is being grafted and how it is placed.  Fat grafting is a highly skilled procedure, requiring a surgeon with experience and knowledge to perform it successfully.  The survival of the fat will depend upon those skills and will be the result of how the fat was harvested, how it was purified, and how and where it was injected.  Specifically, a process called ‘micro fat grafting’, though labor intensive, is the best way to ensure that the highest percentage of grafted fat will take.

When done successfully, the injected fat grows a new blood supply and begins to receive the nourishment it needs to survive from your body.  When this happens, results can and often are permanent.  However there can be a percentage of fat that does not take and this is why touch-ups are sometimes necessary.  It is important to discuss options in advance to determine the best course of action for your situation.
