Is the effect of Density High, which claims to tighten sagging jawlines, really dramatic?

Every time I look in the mirror, I feel like my jawline is sagging, so I'm searching extensively for lifting devices.

Thermage is too expensive for me to even consider, but Density-High, a similar radiofrequency device, seems to be really popular these days. I’m intrigued because I hear it is minimally painful yet highly effective, so I’d like to know just how noticeable the effects of Density-High are in actual practice. Will my jawline tighten and my skin become visibly firm?

I've heard that Density High improves over time because collagen is generated, rather than immediately after the procedure. I'm curious if this is true. Since it is a bit pricey, I want to make a careful decision. I would appreciate honest feedback from those who have actually received the treatment! I want to regain my firm, toned facial contours!
