Nu Skin Galvanic Spa
You're much better off getting a proper galvanic machine and a much wider variety of options. It's been quite a while since I looked at the NuSkin device, so can't remember anything specific, but it was a very limited machine. Galvanic current can either be used for disincrustation where the sebum in the skin is turned into soap by the current and so easy to clean, or iontophoerisis, where it pushes product into the skin to plum it up. With teh handheld units like the NuSkin one, it's not really doing much, it's mainly the actual product doing most of it. A more powerful unit gives better results, but they don't want you using their product with a different device, which I thought was very very strange, though probably indicative of how people buy things and don't use them - they make more money sellign teh device than the consumables.
