It took about a week after getting Density to understand it a little.

Honestly, at first, I wasn't really sure. Even on the day of the procedure, I kept looking in the mirror, but I didn't feel much different from usual. So I wondered if it wasn't working, but a few days later, while washing my face, I touched the area around my jaw and felt it was firmer than before.

It wasn't a dramatic change that was immediately noticeable, but since that was exactly what I wanted, I was actually fine with it. Even if I get it done again in the future, I don't think I would judge the result right away.
