I would like to know the recommended number of times for a double chin.

As I get older, I can feel my facial contours sagging, and I am incredibly stressed about the double chin that stands out every time I look in the mirror. Since the fat on my double chin just won't go away even with exercise, I finally decided that I needed to get help from a procedure.

I am looking to refine my double chin line through procedures like Shurink or InMode. How many sessions is typically recommended to see noticeable changes? I am writing this post to ask if a single session is effective, or if I need regular treatments to maintain the line.
