Non-invasive skin toning device using microcurrent technology. I've had this device for a few years and didn't use it regularly for the majority of the time. I recently bought a new medical spa grade device, so I'm selling this one. The gold coloring is rubbing off but that does not impact the way the device works; it works perfectly. I no longer have the box or original conduction gel. I use this gel, as it's much more affordable and does the same thing: https://a.co/d/1mHn8qQ
