How long does the Shrink Universe procedure take?

I am considering booking a clinic appointment this weekend to get the Shurink Universe treatment. How long does the actual treatment take?

As an office worker, I have to squeeze in a quick visit after work or between weekend schedules. I heard that the Shrink Universe has a much faster shot delivery speed compared to existing equipment, so the actual treatment time is completed quickly, within about 10 to 15 minutes.
I am curious about the actual pure treatment time when the device is applied and fired, when receiving about 300 or 400 shots to the entire face.
Also, I would like to know how many minutes I need to stay at the hospital in total, including the waiting time for the anesthetic cream to be applied and post-procedure soothing care, and whether it is something I can easily get done within an hour on my way home from work and go home.
I am also concerned about whether my skin condition qualifies me for the Shurink Universe recommendation. I don't have a lot of fat on my face overall, but I am worried that as I get older, the double chin line has started to sag slightly and my jawline contour has become blurred.
I looked it up and heard that Shrink Universe is the perfect recommendation for people who want to refine lines in specific areas. I am curious if you have experienced a lifting effect that tightens only your sagging jawline without any side effects like cheek hollowing or sunken cheeks, even though you have a thin face like me.
I would be very grateful if those who have already received this could share honest reviews or advice on which skin types or concerns typically yield the highest satisfaction.
