How many months should I schedule the procedures at intervals?

I heard that Shurink Universe is faster and much less painful than the existing first-generation Shurink, so I'm really tempted to try it. Haha. Compared to expensive ultrasound lifting equipment, the price is quite reasonable, but I'm wondering if the lifting effect lasts longer and if I'll have to keep getting treatments every few months. Is there a reason for the low price? How is the pricing structured at Maypure? I am mainly considering the procedure to smooth out my sagging jawline and the skin around my mouth. I would like to know how often I should schedule treatments to maintain the lifting effect for a long time without putting a strain on my skin.
