From the photos, it appears that the hollow cheeks are really emphasizing the jawline and that the former, not the latter is the main issue. Happily, nonsurgical cheek augmentation with the use of volumizing fillers has become quite routine these days among experienced injectors. My choice for this purpose in my Upper East Side Manhattan practice would be a combination of Radiesse and Voluma XC. Results are immediate and typically last up to two years. In my Israel satellite facility, where a far greater number of regulatory agency approved fillers and volumizers are available, I would opt for a combination of Emervel Volume and Teosyal Deep. I am not much of a fan of Sculptra, since it is not a filler, so it does not give an immediate improvement, requires a series of three treatment sessions, and is relatively expensive. I am also not a fan of fat injections. This, too, is typically a multistep process, requiring one procedure to withdraw the fat from the flanks, abdomen or buttocks, and the second procedure to inject it. And despite the claims that the results are permanent, one study evaluating fat transfer for mid-face volume augmentation (your area of interest) showed that less than a third of the initial volume injected remained after 1.5 years. Seek consultation with a board certified aesthetic core physician with experience and expertise in deep support volumetry, which is the fancy way of saying a three dimensional approach to facial volumizatio using volumizing fillers n to provide proper lift, projection and light reflection for the face. Make sure to ask to see before and after photos.
