Review (5/5): Upgrade kit for the NuDerma Standard and Professional
These wands turn any NuDerma Standard or Professional into the "Clinical" version. They contain a mix of Neon and Argon gas, and glow a weak blue color under dim light (this is normal). The blue tubes are said to give the best of both- Neon has more of a Diathermy (local heating/warming) effect, while Argon is said to have stronger effect on Acne and other skin conditions. If you broke any of your wands or enjoy your High Frequency device and want to upgrade the tubes, this is a solid choice.
