For those who have received Density High Lifting, what is your impression of the effects and cost?

I feel my facial contours becoming blurred and my skin losing elasticity, so I am seriously considering a radio frequency lifting procedure. I am a bit concerned about cheek hollowing with HIFU lasers like Ulthera, so I am leaning toward Density-High, which firmly replenishes collagen deep within the skin. I heard that it emits both unipolar and bipolar radio frequencies simultaneously to firmly tighten elasticity from the deep layers of the skin to the surface.

Furthermore, I’ve heard that it has the advantage of a gas cooling system, making the procedure much more comfortable compared to conventional radiofrequency treatments. However, since it uses genuine tips and involves multiple shots, the cost per session seems quite steep. I would like to ask for advice from those with experience on how many shots are typically recommended for Density-High, and whether the treatment is worth the money given the 확실 effect of tightening facial lines relative to the cost!
