When does the Volneumer effect start to appear?

Lately, I have been looking into the Volneumer procedure to improve my facial elasticity and contours. I became interested because it is a radio frequency lifting treatment, but I am asking this question because I am curious about when the actual effects will start to appear.

I am curious whether I can notice a change immediately when looking in the mirror after the procedure, or if the effects appear gradually after a few days or weeks. I am particularly hoping for a more defined jawline and cheeks, so I would also like to know at what point those who have actually received the treatment felt the most significant changes.
