How are the effects of Denserty-High?

Lately, my face feels like it looks swollen all day long. Do you know what I mean? You know that look where, even after the swelling goes down following a night of heavy drinking, you still look incredibly tired and as if you slept for over 10 hours, haha. I asked around, and people told me it looks that way because my skin is sagging and my jawline has collapsed, suggesting I try a procedure like Thermage. Hearing that immediately reminded me of Densor T-High, which Lee Young-ae is currently advertising. For those who have tried Densor T-High, how does the effectiveness compare to Thermage? Do you see immediate results from Densor T-High? I'm curious about the level of pain and dryness. Also, I'd like to know if Densor T-High improves a sagging jawline, if I need a separate procedure to manage that, and how to care for it afterward—specifically, the treatment schedule. Please share your experiences if you were satisfied with the Densor T-High procedure.
