Will fat transfer and PRP fillers migrate like hyaluronic acid fillers?

So the verdict is out that fillers are not the way to go because your body doesn't really absorb them, they just migrate to other parts of the face. What about with fillers using your own body fat and platelet rich plasma . I've heard that using these two together strengths and increase the amount of fat that survives, but does fat migrate does PRP migrate . It is from your own body so why would it . What is the 5-10 year appearance underneath it all for these procedures?
