Density High Inquiry

Hello. While considering a skin tightening and lifting procedure, I learned about Density High, a radiofrequency device, so I am leaving a few inquiries before the procedure.

From what I have learned, Density High is characterized by its ability to deliver energy evenly from the shallow to the deep layers of the skin. I have tried other treatments, but I haven't had Density High yet, so I have some questions.

In this regard, I would like to request your professional response regarding the following three points.

Timing of Effects: When do the improvements in elasticity and tightening effects through collagen regeneration usually become noticeable after the procedure?

Duration of effect: I would like to know how long the effect lasts after a single treatment and what the recommended treatment cycle is.

Side Effects and Pain: I am sensitive to pain. I would like to know if the procedure is comfortable enough to undergo without general anesthesia or special anesthetic cream, and how long the redness lasts after the procedure.
