My facial elasticity has dropped drastically; will the Density High procedure take a long time? ㅠㅠ

My skin is naturally on the thinner side, and lately I’ve been seeing its elasticity drop rapidly in real time, which makes me so depressed ㅠㅠ Fine lines have gotten really deep, and pillow marks don't go away for over half a day, so I’m planning to improve my skin's fundamental condition! I heard that high-frequency technology really tightens and boosts elasticity. Density High I'm seriously looking into lifting procedures haha. Since I'm a working professional, I want to make time to stop by a dermatology clinic after work, but I'm looking into everything from the anesthesia to the finishing touches. Density High I'm really curious about roughly how long it takes. Also, I'm a little worried about sunken cheeks, but even someone with thin face can get it done. Density High I would be really grateful if those of you who have received this treatment consistently could share your genuine reviews to see if it just tightens your skin or if there are any side effects lol
