Is it a waste to have Ultherapy when I’m going to have a face line surgery in 5 months?

I’m interested in doing Ultherapy regularly to slow down aging process. I want to do it now, but I’m planning to have facial lipo and masseter muscle removal in 5 months. I plan to do Ultherapy after the surgery too. But I’m wondering if doing it now, 5 months earlier, will be a waste because the tightened part of my face will be removed during the surgery. For anti-aging purpose, is it better to wait to do Ultherapy until after the surgery? Or should I do it now AND after the surgery?
