What is the recommended number of sessions for Density High elasticity lifting?

It makes me so depressed because I can feel my overall skin elasticity dropping rapidly as I get older. ㅠㅠㅠ My nasolabial folds are getting deeper, and my cheeks seem to be sagging. I am especially worried about the fat in my cheeks.

So, I’m looking into radiofrequency lifting. Lately, I’ve seen really good reviews on online communities for the Density-High treatment, noting that it features a cooling function to reduce pain while providing powerful results. I’m wondering if a single session is effective, or if I need to receive it consistently over several sessions. How many Density-High sessions would be the minimum required to see noticeable facial contours and firmness? I know it varies depending on individual skin condition, but if anyone knows the typical recommended number of Density-High sessions advised by clinics, I would appreciate it if you could leave some tips in the comments!
