When does the Volneumer effect start to appear?

Hello. Lately, I feel like my facial sagging and jawline have deteriorated significantly compared to before, so I was looking into lifting procedures and came across Volneumer. I became interested because it is a radiofrequency lifting treatment, but since this is my first time receiving it, I am asking this question because I am most curious about when the effects will start to appear.

I am curious whether I can feel a slight tightening or improved elasticity in my face immediately after the Volneumer procedure, or if it takes a few days or weeks for the full effects to appear. When I search online, some people say they felt results right away, while others say their condition gradually improved over time, so I would like to know what it is like in reality.

In particular, I am curious about when the jawline or sagging cheeks will start to improve after receiving Volneumer. I would also like to know if my face might look slightly different immediately after the procedure due to swelling.

I am also curious about how much change I can expect from a single treatment. I would like to hear actual experiences regarding whether this procedure dramatically alters the facial contours, or if it simply makes the skin firmer overall and provides a natural lifting effect.
