Does PRP prior to Ultherapy have any effect on the Ultherapy results?

Hi, I am 35 y, had Prp injections 3x with 4-5 weeks apart, then 1x of Ultherapy treat mild sagging of the jaw and droopy lip corners, my face was not particularly fat (treatment lasted about 35 min) with a machine Ultraformer 3. I felt the machine was aggressive, it hurt, I had shots with 1.5mm 2mm and 4mm head. Unfortunately only after I had the treatment noticed horrible volume loss stories which had to be treated with PRP. Does my previous PRP help to prevent the possible volume loss?
