How satisfied are you with Density High for your sagging jawline?

I'm not particularly overweight, but as I get older—perhaps due to gravity—the skin under my chin has started to sag, and my face has begun to look asymmetrical. It's stressful because my lower face stands out so much whenever I look in the mirror, so I've been looking into radiofrequency devices. That's how I found out about Density High. I'm curious if those who have actually received the treatment felt the tightening effect on their lower jawline. Also, if I want to focus intensively on the jawline, is 300 shots of Density High sufficient to define the lines? Or, since I'm spending the money anyway, should I go for a generous dose to see a noticeable lifting of my sagging chin? I'm really debating the dosage...

I am also worried that if I increase the number of shots too excessively, I might experience side effects such as weight loss or uneven skin.

I'm planning to go around for dermatology consultations and sign up for a package soon. Has anyone started Density-High for sagging jawline care?
