How severe is the pain in Volneumer?

Lately, I feel like my facial elasticity has decreased and my jawline has become less defined than before, so I am looking into lifting procedures. While researching various treatments, I came across Volneumer. I am curious about the effectiveness, but I am most concerned about the level of pain, so I am asking this question.

I heard that Volneumer is a procedure that uses high-frequency waves. Is it actually quite painful during the treatment? I am curious if it is just a stinging sensation, or if there is a strong burning or tingling sensation. Since I tend to be sensitive to pain, I would also like to know how much I should be prepared for before the procedure.

I am particularly curious if there are differences in pain depending on the facial area, such as the cheeks or jawline. I would also like to know if the sensation varies by region, such as the forehead, temples, and around the jaw.
