I have a question regarding the cycle and number of sessions for leg lifting.

I recently learned about Ondari Lifting while looking into lifting procedures, so I am asking this question because I am curious about the number of sessions and the treatment cycle.
I’ve heard that Ondari Lifting is usually done about 3 times at one-month intervals, but I’ve also heard that just one session is enough depending on your skin condition. For those of you who have actually had it done, how did you handle it?
It is a bit puzzling that there can be such a difference with the same procedure.
I am considering treatment for my jawline and double chin, and I am wondering whether I should try one session first and then decide, or if it would be better to plan for about three sessions from the start.
If not that, I wonder if there are people who do it more times.
If you have any experience, please let me know how many Ondari Lifting sessions you have received and how often you spaced them out!
