Which is the Best Dermal Filler for the Hands?

Volumizing and hydrating fillers work the best for hands.  Restylane silk, Restylane Lyft, Radiesse, Sculptra, Bellafill are some fillers in hands that work well.  If it's your first time, I would start with Restylane Silk.  It's both hydrating and volumizing and it's a thinner filler than the rest. 

In my experience free fat grafting or sculptra are the best for rejuvenating the hands. The fat is a first choice because it has the best feel and longest term result (permanent) if the fat survives the grafting process. My personal preference is not to use other types of fillers in this area because of natural feel, effectiveness and risk of complications.
