Does the sensation change when you bend your head down after receiving Ulthera?

These days, when I look down at my phone
I am particularly bothered by the skin folding under my chin.

It's usually not very noticeable from the front, but
If you look down, you can clearly see the sagging part.

With Ulthera, not only the facial contours viewed from the front
I am curious if the visible part changes when I lower my head like this.

Because it is a change that is difficult to compare with photos
I am also curious to know in what situations those who have actually received it experienced it.
