How often do you usually get Ultherapy?

I am considering getting Ultherapy repeat treatment, and I am most curious about the treatment cycle.

The recommended intervals vary slightly from hospital to hospital, ranging from 6 months to 1 year to 1.5 years, so I'm confused about which cycle is appropriate.

They say the effects tend to last a long time,

I am worried because I’ve heard that receiving it too often can put a strain on the skin or lead to fat loss.

Conversely, I am also wondering if I have to receive it again after the effect has almost worn off if I wait too long.

For those who have actually received Ultherapy, how often do you usually get the treatment every few months or years?

I would appreciate it if you could share your experiences, how long the results last, and your satisfaction level regarding whether once a year is sufficient or if you get it done whenever you feel sagging.
