Has anyone tried the Onda Lift for sagging under the chin?

Hello

As I get older, I am concerned about my jawline sagging and fat accumulating under my chin. I heard that InMode leaves marks, so I am looking into Onda Lifting, which is said to cause less bruising and pain. I heard that it uses microwaves to reduce fat and improve skin elasticity.

I've heard that there are minimal side effects or downtime, but I'm curious if it is truly effective for double chin reduction. I'd like to hear reviews from people who have actually tried it regarding how many sessions are typically required to see a defined line and how long the effects last. Can I see some results after just one session?
