Components of a non-ablative bipolar fractional microneedle radiofrequency device (Inus^TM). A main body and a hand piece (A), schematic diagram of action using a temporary tip with peripheral vacuum edge line (B), and image of the twenty-five numbers of fractional needles located in the center of the tip (C). (D) The entire length of the needle is 3.5 mm and its thickness is 0.12 mm. The distal part, 0.5 mm in length, is non-insulated, whereas the proximal part, 3.0 mm in length, is insulated with gold.
