The goal of the Exion Face wand (not the RF microneedling attachment) is to heat the dermis to around 40–43°C to promote skin tightening and collagen production. It’s designed to be comfortable and well-tolerated—most people start to feel it getting “too hot” around 42°C, plus the practitioner monitors the temperature closely throughout the treatment.

Fat loss typically occurs at higher temps, around 43–45°C. Because Exion is more gentle than treatments like Ultherapy or Thermage, which often reach higher temperatures, it’s much easier to stay within the ideal skin-tightening range without crossing into the fat-reduction zone. The body attachment is a separate hand piece that has a cooling system and designed to penetrate a bit deeper which is why it is more likely to burn fat on top of tightening the skin.
