Does Ondari Lifting really have a noticeable effect on sagging jawline?

Lately, whenever I take a photo, my jawline sags, making my face look wide and flat. Since contouring injections only provide temporary effects, I was looking for a semi-permanent lifting treatment and found out about Onda Lifting, which is supposedly very popular these days. I heard it uses microwaves to break down unnecessary fat and replenish collagen, so I thought it would be perfect for my double chin concerns. However, I'm not entirely convinced that Onda Lifting is actually more noticeable than Ultherapy or Shurink when it comes to tightening jawline fat. For those of you who have received Onda Lifting for sub-chin fat and deep cheek sagging like me, I'm curious to hear your honest reviews on whether you definitely felt the line tightening. Any feedback would be incredibly helpful.
