What are the advantages of Density High? How is it different from other radiofrequency lifting procedures?

I was concerned about sagging skin elasticity and was looking into lifting procedures when I learned about a device called Density-High. I am curious about the differentiating features of this device compared to existing radiofrequency lifting procedures like Thermage or Oligio, as well as the advantages of Density-High.

I would like to know if this method uses both monopolar and bipolar radiofrequency energies simultaneously to care for both the skin surface and deep layers at once. It also seems like a major advantage that Density High's cooling system works well during the procedure to minimize pain; is this true?

I would like to hear a detailed explanation on whether this Dencerty High procedure is a much more cost-effective choice than other lifting procedures in terms of cost-effectiveness and satisfaction, so that I can make a decision.
