56, face is heavy on bottom, buccal fat removal, Botox and fillers or...? (Photos)

I am 56 and had a deep plane face lift 1 1/2 years ago. I had mild nerve damage which has largely resolved. I feel my face is now very heavy on the bottom, especially when I smile, both at the back (where the skin may not have been pulled tight enough) and especially in the chubby cheeks I have when I smile. Can you please recommend whether Buccal Fat Removal, masseter muscle botox, cheek filler or some combination would help with this? Thank you.
