Thank you for your question on cheek augmentation with Voluma. Juvederm Voluma is a smooth, dense product that is FDA approved for mid-face volumization and has been found to last up to 2 years. It is injected deeply, right over the cheekbone to give support and lift to the mid-face. We place Voluma starting with the upper, lateral cheek as this provides the best lift to the mid-face (including naso-labial folds). This technique results in a higher, more rounded and youthful curve to the face and can even help improve the look of the under eye ("tear trough") area as well as corners of the mouth. The amount of Voluma used varies from patient to patient, depending on their age, quality of skin, volume loss, and sagging. An average of one per syringe per side is very common, but some patients may need more and some less (eg a more deflated balloon requires a greater amount of air for reinflation compared to one that's lost very little air). It's important to seek out an experienced, qualified injector who has extensive experience in order to achieve your best and safest result. In our office, we have Master Injectors who are experts in the most advanced injection techniques - giving our patients excellent, natural-looking outcomes.
