When does the density effect start to appear?

Hello. Lately, I feel like my facial elasticity has decreased compared to before, and my cheeks in particular are sagging a bit, making my jawline feel less defined. So, I am looking into lifting procedures. While researching various treatments, I came across Denserty. Since this is my first time receiving this procedure, I am most curious about when the effects will start to appear, so I am asking this question.

I heard that Denserty is a lifting procedure that uses radio frequency. Can I actually feel my face tightening or notice improved elasticity immediately after the treatment? Or do the effects gradually appear after a few days or weeks rather than right after the procedure?
