A Thank you for your inquiry. Ideal treatment of midface volume loss is achieved with at very least one syringe per side to achieve a natural contour... most of the time. In your case I would suggest that you begin with 2CCs and return in 2 weeks for evaluation as it takes time to really see the result. Although you can see instant results with Voluma, at Neoskin Center we like to do a followup and add if needed to achieve the best results for each patient individually. Once you get the result you desire it's quite simple to add one syringe total as needed to maintain.
