How severe is the pain or swelling during a density high?

Among recent lifting equipment Density High I heard rumors that it is effective because it delivers high-frequency energy deeply. Compared to conventional lifting Density High I've also heard that the pain is much less because it has a good cooling system. Since my skin is thin and I tend to be sensitive to pain... Density High I am wondering if the procedure is tolerable enough without general anesthesia. I would also like to hear reviews on whether severe swelling immediately after the procedure interferes with daily life, and whether you experienced immediate tightening effects.
