Density Lifting Effects: When did you notice a change in your skin elasticity after the procedure?

Lately, I've really felt like my facial skin isn't what it used to be. In particular, my cheeks seem to be sagging slightly, and my jawline looks less defined than before, so I am looking into lifting procedures.

While looking into various things, I found out about a procedure called Denserty. I heard that it helps improve skin elasticity by using high-frequency energy to induce collagen production deep within the skin.

What I'm curious about is how much of a change I can actually feel when I get the procedure.

I am also curious whether I feel a slight tightening sensation in my skin immediately after the procedure, or if the elasticity gradually improves over time.

I would especially like to know if it is effective for the jawline, sagging cheeks, and around the nasolabial folds.

I would like to hear from those who have experienced it about whether a single session is enough to see satisfactory results, or if it is a procedure that requires consistent treatment.
