Is fat transfer the best way to fix malar fat pad? (Photo)

Unfortunately you have a challenging problem for which there is no completely reliable solution. Fat grafting can often help but in general will improve rather than completely fix the line. Malar swelling after facelift can last for many months. I Woukd wait a few more months before proceeding with fat grafting and choose a surgeon with a lot of experience.

Fat grafting is a good technique for filling the malar area
It usually takes more than one procedure.
