Which would you recommend; Voluma or Radiesse?

I have not placed a single syringe of Radiesse in the cheek since Voluma was brought to market in the US, so my answer to your question is easy to decipher. Not only can Voluma be reversed if you were to have a rare complication from injection but it also lasts longer. In my opinion, Voluma also creates more lift and looks more natural. You will likely encounter a variety of opinions but I think that this is a very easy decision.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Both products are very reputable. In my experience you can get similar results with both products. However the longevity maybe longer with Voluma.  If you have never had cheek augmentation with fillers, then using Radiesse may be a good first line option. As the volume depleats, you can replace with Voluma.  Other good options for cheeks include Perlane.  One other long-term option is Sculptra.
