For those of you who have received Volneumer, what changes did you notice?

Lately, when I look in the mirror, I feel like my facial contours have become less defined than before, so I am looking into ways to improve skin elasticity.
While comparing various lifting procedures, I learned about a treatment called Volneumer. I heard that because it uses a radio frequency method, it helps with skin elasticity and body contouring.

However, the changes felt vary slightly from review to review, so I am curious about the actual experience.
I would like to know if there were any noticeable changes, or if you just felt your skin became a little firmer.
For those who received it, what aspects were you satisfied with?
