How long did the tightening sensation on your face last after receiving Density? Is it different from the feeling of your skin becoming firm?

I've heard quite a few people say they felt a tightening sensation in their face after the procedure. I'm asking this because I'm curious whether this is just a temporary tightening caused by skin irritation, or if it's a change felt as their elasticity actually improves.

For those who have actually received Dencerty, did you feel a tightening sensation in your face immediately after the procedure? I am also curious if that feeling appeared the next day or after a few days. It would be helpful if you could also let me know how long it usually lasted.

What I'm curious about is the difference between a simple tightening sensation and the feeling of the skin becoming firm. I'm also wondering if the skin felt slightly stiff when I moved my face, or if it felt like the skin itself became tighter and my jawline was defined.
