What procedure(s) would be recommended to fix my sagging chubby cheeks? (Photo)

From the photos provided, it would appear that an appropriately robust HA volumizing filler can be used to contour a more oval, heart-shaped, feminine face shape. Doing so would likely not only improve the cheeks, but secondarily improve the under-eye hollows and incipient tear troughs above and even improve the nasolabial folds below. An additional HA filler chin augmentation and also injected along the jawline would not only harmonize the projections of the chin, lips and nose in profile, but also lead to a tighter, more defined jawline and tightening of the upper neck below the jawline. All of the above, in the hands of an experienced, board certified cosmetic dermatologist injector can be performed in about three quarters of an hour session with on-the-spot results and little to no significant downtime. The hard science to support the use of the many of the expensive light and energy-based gizmos being so heavily hawked out there these days for these kinds of issue is weak, so, it would be wise to exercise a great deal of "buyer beware" caution before considering those options. Hope this helps and best of luck.

Volume and contouring of the cheeks can be created with well-placed fillers (Voluma, Radiesse, Bellafill, Contour) and Sculptra. Implants or fat are alternatives. Botox and radiofrequency can help slim and contour the jawline. Liposuction can help slim the face. Ultherapy, J Plasma and rf treatments can provide skin tightening and lift. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer
