How are the effects of density highs these days?

I learned about the Density High treatment, and I became very interested because I heard it can care for both the deep and shallow layers of the skin at once.

Since the procedure involves delivering high-output energy to the skin, I am unsure about the level of heat or tingling pain I might experience during the treatment. Even with the cooling system activated, is the pain severe enough to be unbearable without anesthetic cream? I am also concerned that patchy redness or irritation might persist for several days immediately after the procedure, potentially interfering with my daily life.

If anyone has actually experienced the Density High treatment at a dermatology clinic, could you please share a vivid review regarding how many shots were typically required to achieve a noticeable improvement in skin firmness?
