Fillers don't work because of my skin. What can I do? (Photo)

Hi, I've posted several questions regarding a flat and hollow part around mid cheek in my right cheek and some doctors answered fillers would help...I did fillers and although it helped with volume, I still have a flat area and line in mid cheek, the flat area creates a big shadow...It looks like herniated skin, is there something I can do to make the cheek smooth? I appreciate your options, thank you!
