Here’s a video on the proper usage of ReFa Pro. What I like about this tool is that you don’t need to add batteries and neither do you need to run it via electricity. The best part is, you can use it wet or dry. And besides the micro-current treatment, the ceramic rings contained in the angled rollers of Refa Pro are made up of 16 different natural ores such as Amethyst, Tourmaline and Germanium. The unique combination of these 16 natural ores has been fine-tuned for cosmetic purposes and achieves additional effects of lifting and detoxifying.
