ThermiRF is the company and platform for all THERMI procedures that include ThermiTIGHT, ThermiSMOOTH, ThermiVA, and Thermi250. They all use radiofrequency to tighten or remove fat. ThermiTIGHT is minimally invasive (goes under the skin thru small needle holes) while the others are non invasive and are only applied to the skin. I have all of these platforms and they all work great in the right hands - i.e. they are all user dependent! Each does something a bit different and is best for different areas. Ask your Thermi doc to see which areas are best for what in their practice. I find that ThermiSMOOTH is great for eyes, cheeks, mouth, and foreheadThermiTIGHT is great for the neck/lowerface, body, knees/thighs, arms, breast - and more!!ThermiVA is for vaginal tightening and limited external labia majora and minora tightening or firming upThermi250 is a bigger version of the ThermiSMOOTH and noninvasively removes fat and tightens skin on the body - i find it works great in the abdomen, chest, thighs, knees, and arms
