For those who have tried Density High, how were the effects?

Lately, even though I don't have much fat on my face, I can see my cheeks and jawline gradually sagging downwards, and it is really frustrating every time I look at it.

While looking into various skin firming devices, I noticed that Density High seems to be getting a good response these days. I am very interested because it uses both monopolar and bipolar high-frequency energy to simultaneously fill in density and firm the skin from deep within to the surface.

But since there are so many promotional posts, I'm not sure if it's actually worth the money to try it out.

For those of you who have actually received the treatment, can you definitely feel your jawline or the lines around your mouth becoming firmer, as if they are clinging tightly to your facial bones?

I would like to know if the results are noticeable immediately after the procedure or if it takes a few weeks for the plumping to become visible. I am also curious to hear real-life experiences regarding how long that firming sensation lasts. For those who have tried Density High, please share your thoughts on the effects.
