When the effects of Ultherapy wear off, does my face feel like it sags suddenly, or does it gradually return to a natural state?

I am asking this question because I am curious about those who have actually received Ultherapy. I am also curious about how long the effects last after the procedure. I would like to hear from those who have experienced it about how the effects diminish over time, even though the facial contours were clearly defined at first.

I am curious if, during the initial period when the effects were good, the jawline or sagging cheeks definitely felt improved, but then gradually return to their previous state after a few months? Or if there is a moment when elasticity suddenly drops, giving the feeling that "the effects have worn off."

I am especially curious to know how it went for those who compared photos, as I feel like I wouldn't notice much of a change if I looked in the mirror every day. I would like to know if the jawline became less defined first, if skin elasticity decreased first, or if sagging started reappearing in areas where you are concerned, such as nasolabial folds or the corners of the mouth.
