Density High for refining contour lines

Hello. I am writing to inquire about refining my sagging jawline and double chin ahead of an important upcoming event.

I felt that I needed care that tightens the skin from the deeper layers rather than just the surface, so I started looking into the Denserty High procedure.

I am curious about how long it takes for traces such as bruising, redness, and swelling to subside after the procedure. To ensure Density High fits my schedule, could you recommend visiting a few days before an event for the most effective results? I am also wondering if there is a significant difference in the immediate contour improvement effects unique to Density High compared to other radiofrequency lifting treatments I have received in the past.

Could I know in advance the approximate number of shots and price range when focusing on the cheeks or under the chin?
