At least from the one cropped photo provided, ti would appear that the use of a robust, HA volumizing filler would not only help to contour a more oval, heart-shaped face, but would likely secondarily improve the under-eyes without even the need for additional filler there. I encounter this kind of situation very frequently in my practice and very often find that no additional tear trough filler treatment is required. The use of a robust HA filler for the cheeks can often yield durable results of up to 1.5 years. I stopped using fat injections a very long time ago. Admittedly, the idea of using one's own fat and the promise of permanent results is enticing. However, the reality is that much of the fat, once separated from its original blood supply in the thighs, abdomen or buttocks does not surprise. What's more the fat injection therapy is relatively expensive process and engenders downtime, since fat must withdraen with large cannulas from the donor sites and injected via large cannulas into the recipient sites. And finally, any fat that does survive this process retains the characteristics of the area from which it is taken, meaning that with the passage of time belly fat will develop a midriff bulge, any fat transplanted into the face that did survive may also develop bulges. You would be wise to consult with a board certified cosmetic dermatologist filler expert. Best of luck.
