Need help with volume and fat loss from Ultherapy - what treatment(s) would be recommended? (photos)

I had ultherapy 3 months ago hoping it would tighten areas in my lower face that suffered loss of collagen from old acne scars + aging. I'm 42, always had a chubby face that made me look younger than my age. Now that I've had ultherapy, I have sagging and volume loss at my cheeks that I never had before. So the issue that I went in to fix got worse. I'm pretty devastated. I had my follow up w/the doctor and he noticed the missing volume & rec'd fillers.
