What procedures would be best for premature sagging and early jowling? (Photo)

I'm almost 30, and within the last couple years, I've really noticed changes in my face, such as volume loss and a heaviness in my jawline towards my chin. Weight seems to be settling around my mouth. I'm very opposed to fillers in the face, and would much rather a more permanent solution. Would facial fat transfer be a good option if I'm looking to restore balance to my face?
