In regard to Cosmodic devices, do you just turn it on and wave it around like a magic wand so to speak and it takes care of the rest?”
Cosmodic’s are fully automatic. They turn on automatically when the electrodes touch the skin and the energy (power) level is also adjusted automatically during treatment. They have automatic diagnosis to show you where to apply treatment and automatic dose where the device signals when treatment has finished. If you leave your Cosmodic on after you have finished your treatment, it will even turn itself off after two minutes to save on batteries. So as you can see it is very simple to use. The EX735Ag goes further in that it will also select either Scenar or Cosmodic modes automatically depending on what the body needs. For the more experiened users, it also has manual settings.
