I have so many questions about Density. I am asking you.

Lately, my skin elasticity has decreased and my facial contours don't seem the same as they used to be, so I am looking into lifting procedures.
Then I found out about Density, and I became interested because there were more reviews than I expected.

I am wondering if it is particularly effective for sagging cheeks or tightening the jawline.
I would also like to know if I feel a lifting effect immediately after receiving it, or if the effects appear gradually over time.
I am also curious about how long the effect usually lasts.

I am also curious about the advantages of Dencerty compared to other lifting procedures like Thermage or Ulthera.
Please let me know if the pain is tolerable, and to what extent there might be swelling or a burning sensation after the procedure.

Also, it seems like there is quite a price difference between hospitals, so I'm struggling to decide what criteria to use when choosing one.
Are things like the number of shots, the type of tip, and the director's experience also very important?

I am also curious to know if those who have actually received Dencerty were satisfied, and whether the effects were most noticeable after a few weeks.
Please share honest experiences from those who have actually used the product, not promotional reviews!
