I would echo Dr. Persky's sentiment - with a few additional points.
In patients who are interested in lip augmentation, there are temporary solutions and permanent ones. Currently there are several permanent solutions for lip augmentation including fat transfer (transferring fat from the belly or thigh to the lips) and silicone or ePTFE implants. I favor fat transfer to implants because fat is the patient's own body material and not a foreign substance which is introduced. This decreases the risk of infection and extrusion.
In my patients who are considering a fat transfer to the lip I strongly recommend a temporary filler first. The good and the bad part about temporary fillers such as Juvederm or Restylane is that they are temporary. If you do not like the results, they will go away in a matter of a few months, but if you like the results you will have to come back for another treatment or a more permanent solution. By going with the temporary filler first, patients are able to see what the expected results would be with fat transfer and decide if they like them. If so, we can proceed with fat transfer once the filler has gone.
