Does Volneumer have an effect on facial contouring?

Lately, I've been a bit self-conscious about my facial contours whenever I take photos or look in the mirror, so I'm looking into Volneumer. In particular, my jawline feels less defined than before, and my cheeks seem to be sagging slightly, so I started looking for lifting procedures and found out about Volneumer.

I understand that Volneumer is a radiofrequency lifting treatment, so I am curious if those who have actually received it felt a noticeable improvement in their facial contours. I would like to know if it simply makes the skin firmer, or if the overall contour of the jawline or cheeks also looks slightly different.

I am also curious whether the effects are visible immediately after the procedure or if changes gradually appear over time. If anyone has had the treatment focused on the jawline or cheeks rather than the entire face, I would appreciate it if you could let me know which areas you were most satisfied with.
