Who would benefit from the Density High procedure?

I have recently become interested in Density-High while looking into skin firming and lifting procedures, so I am currently researching information about it. People around me recommend Density-High, saying it is effective for improving skin elasticity with relatively low pain levels. I am curious to know which skin types and age groups it is actually best suited for. I am particularly concerned about sagging jawlines, loss of elasticity around the cheeks, and fine lines, so I would like to know if it is effective in cases like these. I read online that Density-High uses radiofrequency energy to induce collagen regeneration deep within the skin; I would like to hear personal experiences regarding whether the lifting effect is felt immediately after the procedure or if the firmness gradually improves over time. I am also curious if it is suitable for people with less facial fat or thin skin, and how long the effects typically last. I would appreciate it if you could provide detailed information on Density-High's unique features, advantages, and recommended target audience compared to existing lifting devices like Thermage or Ulthera.
