Emsculpt Neo - RF / Heat Depth

Hi, I read that the HIFEM energy on Emsculpt (and Emsculpt Neo) penetrates to a depth of about 7cm under the skin. The Neo also uses RF to heat adipocytes, disrupting or killing them. Do you know what the penetration depth of the heat/RF is? I wonder if this might heat and damage tissue in your liver/stomach or other internal structures, where you might not even feel pain/discomfort because it is internal. I could not find RF penetration depth in the literature (only 7cm for the HIFEM).
