(1)For the  mrico needle RF handle:used for invasive treatment,4 kinds of  mrico needle tips for choice ,including 18pins ,25pins ,49pins,81pins.   The 18pins tips is situable for the area around the eyes   The 25pins tips is situable for the face reaetment   The 49,81 pins tips is situable for the body treaetment (2)For the fractional RF handle:used for non-invasive treatment, 3 kinds of tips for choice  (3*3 for eyes and nose area, 5*5 for face area, 9*9 for body area) (3)The nagative bar:Our machine has the mono polar mode and Bi polar mode for choice. When using mono polar mode, all the needles on the tip is positive polar. The customer need to hold the negative polar in hand during the treatment. The RF energy can go to more deeper to skin than Bipolar mode.
