Is there significant synergy if I get Skin Botox or Rejuran together with Ultherapy?

I am thinking of using Ulthera to tighten the deep fascia while also using a skin booster to improve surface elasticity and texture.

They really recommended combination treatment packages where you get 300 shots of Ulthera along with Skin Botox, Rejuran Healer, or radio frequency treatments like Oligio on the same day.

I am curious if I can definitely feel a significant synergistic effect in terms of skin firmness and radiance compared to getting Ulthera alone.
