Can Sculptra help with sagging jowls/marionette lines? (photos)

Thank you for your question. Sculptra is a unique type of filler that works by stimulating additional collagen production. Over time, the treatment area becomes fuller and smoother as the collagen works to support the underlying dermal structure. While the treatment takes time to show results, once they become apparent, they are long lasting. 
There are other options for restoring volume to the midface and addressing the early signs of skin laxity and jowl formation along the jawline. I encourage you to schedule a consultation with a board-certified plastic surgeon who can assess you in person and design the treatment plan that will meet your needs and goals best.

There is no substitute for an in-person physical examination that allows for palpation and manipulation of the tissues. However, from the photo provided, it does appear that many of your issues can be easily and quickly addressed via the use of injectable volumizing fillers. For example, your jawline jowls and lack of definition (as well as other regions of the face) would profit from the use of injectable volumizing fillers to elevate the cheeks, enhance the posterior angle of the jaw and restore appropriate shape and projection to the chin--three critical areas for framing the face. Addressing the apparent loss in cheek volume will help to lift and support that region and secondarily improve the lower face and jawline. Likewise, restoring volume to the posterior angle of the jaw will help to straighten a sagging jawline. And finally, enhancing chin projection will likewise soften jowl formation by pulling the anterior region forward, as in youth. In my NY office, I would opt for Voluma XC for the cheeks and Restylane Lyft for the posterior jawline and chin. In my Israel facility, where a far greater number of regulatory agency approved injectable volumizers are available, I would opt for Stylage XXL for the cheeks, Restylane Volyme for the posterior jawline and Neauvia Intense Flux for the chin.  I stopped injecting Sculptra several years ago, since it does not provide immediate "Wow!" results as do the injectables noted above; it requires a series of about three treatment sessions; and is relatively expensive. Additionally, simple fillers, like ordinary Restylane and Juvederm typically used for fine lines and wrinkles will not do the trick for regions requiring volume and if used will not last long. So, be cautious when these cut-rate products are suggested for the locations where you appear to need them and make sure that you consult and receive treatment by a board certified aesthetic physician. . Best of luck.
