What is the typical cycle for your lifting procedures?

Two months ago, I received an ultrasound laser treatment for the first time to address my sagging double chin. I am satisfied every time I look in the mirror because my jawline seems to have lifted quite smoothly. However, the clinic manager told me that the results won't last long with just one session, so I need to repeat the treatment at regular intervals to fully fix the line. I am asking this question because I am curious about how often lifting treatments are typically spaced out—whether weekly or monthly—to ensure the effects accumulate without interruption. I saw reviews on online forums saying that you need to receive lifting treatments about three times at one-month intervals initially for the inner cells to be thoroughly remodeled. Is this true? I am also concerned about potential side effects, such as dry skin or increased sensitivity, if I receive treatments too frequently. It would be very helpful if those who undergo regular lifting treatments to maintain their sagging face lines could share their tips on the ideal timing for visits. I am currently debating when to schedule my next lifting appointment.
