My best description of Synchro is where as Pico and Micro and simple Flash are burst of energy, (just the duration of the blast measures if it is regular thermo, Micro, or Pico Flash) Synchro is a rain of tiny packets of treatment energy that allows one to do thermolysis with the action similar to blend, in that it treats small areas of tissue as you slide in or out of the follicle. Again, it is more site specific as thermolysis always is, but this allows one to move the probe and have small pops going as you are doing a “live probing” of the treatment areas.
I hope this explanation helps. It is hard to visualize if one has no frame of reference.
