Loss of elasticity since entering my 40s—for those who have tried Density, what was your experience?

I didn't used to worry much about skin elasticity, but lately I definitely feel like my face isn't the same as it used to be.

In particular, when I take photos, my cheeks look slightly saggy and my jawline seems less defined than before, so I am looking into lifting procedures.

However, I don't want to get a procedure that is too strong and makes my face feel drastically tightened; I just want my skin to become naturally firm and the sagging areas to be slightly smoothed out.

I don't have much fat on my face, so I also want to avoid looking like I've lost volume.

Then I found out about Density, and it seems like many people in their 40s and older get it for skin firming care. I'm curious if those who have actually tried it saw visible changes in their jawline or felt their skin becoming firmer, or if there were any changes noticeable to those around them.
