Is Ultherapy a procedure only for people with significantly sagging faces?

My face isn't sagging much yet, but
If you compare the photos to the old ones, you can feel that the jawline and cheeks have changed slightly.

So I am looking into preventative lifting.
I'm wondering if I really need a high-energy procedure like Ulthera at my age.

Lifting is not decided based solely on age.
I’ve heard that I need to assess the condition of the skin and the degree of sagging, so I’d like to know what criteria to use during a consultation.
