If you are referring to cheek augmentation, I would recommend Voluma in your situation for 2 reasons:(1) Both fillers have different mechanisms of action. Sculptra stimulates further collagen growth which can take time, and has variable effects based on everyone's own unique metabolism. Voluma, on the other hand, occupies the deep space it is injected to and provides an immediate lift. The result "on the table" is very similar to the long-term result you will experience, which may last up to 2 years.(2) Voluma is the only FDA-approved filler for cheek augmentation. Make sure your surgeon or dermatologist has significant experience with Voluma. As Voluma is a new filler manufactured by Allergan, most injectors' experiences are limited. I would seek out a plastic surgeon in your area who has extensive experience with injecting cheek fillers and typically performs many facial surgeries, as he/she is thus more likely to be familiar with the anatomy in that area, which can be variable even from one side of the face to the other. I would also ask for a plastic surgeon who took the Allergan Expert Hands-on training course specific for Voluma injection.
