How often is a double chin lifting treatment appropriate?

It’s not like I’ve gained a lot of weight, but my jawline looks indistinct, making me feel like I look older than my age, so I started looking into double chin lifting.

However, after looking into it, it seems that a double chin lift isn't a one-time procedure, so I'm curious about the treatment cycle. I'm not sure how long the effects last after a single session, whether I should get another one when the results start to wear off, or if there is a set schedule for the number of sessions from the beginning. Getting treatments too frequently feels burdensome, but I'm also worried that if the intervals are too long, the results might be underwhelming.

For those of you who have had a double chin lift, how often did you get maintenance? I am also curious how long you felt satisfied after the procedure. I prefer a look where my jawline is naturally refined rather than being excessively pulled. Now that I'm in my 40s, I'm wondering if I should consistently take care of my facial contours. I would appreciate it if those who have actually received the treatment could share their routine and how the results lasted.
