With Density, did it take a few weeks for you to see a proper change in your jawline?

I am looking into lifting procedures for the first time, and I am curious because I heard that Denserty is not a procedure that shows immediate results.
My skin hasn't completely broken down, but my biggest concern is that my jawline has become slightly blurred.
So, I was more curious about how much it actually changes over time rather than right after the procedure.
Looking at the reviews, some people said they felt firmer on the same day, while others felt it much later. Is there a big difference?
I am also curious if it usually takes a few weeks for changes in the jawline or lower cheeks to become noticeable.
Are there any of you who were most satisfied after about a month?
Conversely, I am curious if there were any cases where the change was not as significant as expected.
I would also like to know if the difference is more visible in the side profile than the front when taking before and after photos.
I am also curious to know how often those who received it once and were satisfied proceeded with additional sessions.
If you want to naturally refine only your jawline, please share your experience with Density.
