Could the Ultherapy treatment I had done years ago be responsible for scar tissue after my deep plane lift?

I had 2nd deeplane facelift done and results is good. I recall post op the doc told me he saw "moderate scarring/ scar tissues beneath". making the surgery slightly more difficult. So he was rather "restricted" with the procedure for fear of causing nerve damage. Ive had ultherapy done years ago, along with prophilo, rejuaran scar subcision, and Neogen Plasma renew last year. He mentioned Ultherapy could be the culprit. Is this true? Thanks so much!
