Fat vs Restylane as a Filler

Both will give excellent correction with a natural feel. Restylane lasts 9 months to one year, but fat's persistance is less predictable.  If you are younger, fat has a better chance of "taking" as a living graft, in which case it may last for years.  However, most practitioners will tell you that persistance of fat varies from 20-50% in most studies.  Many physicians will take a little more fat than required for the correction and freeze the remainder for later touch ups if needed.
