What kind of treatment is Density High?

Now that I'm in my 60s, I'm secretly concerned about the skin around my cheeks and jawline becoming noticeably saggy and less elastic. I'm already sad about aging because of enlarged pores and deep wrinkles, but I'm also upset that I look older. People around me have been telling me that a procedure called "Density High" is good for skin elasticity and lifting, but I'm curious about how it works to improve the appearance of aging skin.

The name is unfamiliar and a bit scary, but would Density High be effective on skin in my 60s? I'd like to know more, especially about the level of pain and whether there are any concerns about side effects like sagging cheeks after the procedure. I'd also like to hear from people my age who have actually tried Density High and their advice.
