**5. What is the difference between the Morpheus 8 and microneedline and RF micronieeling systems**

The Fractora was the first external Fractional RFAL skin tightening device and was *intradermal Fractional RFAL*. The Fractora is completely different to the safe, but far less effective RF micro needling systems. In all the micro needling systems, the RF energy flows between closely approximated rows of needles having opposite polarity and embedded side by side into the tissue (**Figure 16**). RF micro needling systems have minimal ablative capacity and a very low ablative tissue index. The closely approximately rows of positive and negative pins in the RF micro needling systems lead *to minimal thermal tissue ablation, minimal soft tissue contraction and are basically acting similar to non-thermal micro needling devices.* The RF micro needlers, as I call them offer extreme safety, but negligible thermal coagulation and contraction. They require multiple treatments [6–8], to deliver minimal tissue remodeling, but are quite safe and inexpensive (Micropens often deliver as much).
