Hidrex’s iontophoresis machines rely on traditional metal electrode plates. Whether they’re made of aluminim or stainless steel, these plates will corrode over time due to the very basic/acidic environment. You may notice discoloration on the surface. According to Hidrex‘s own website:
“It is normal for at least one of the electrodes to become discolored after just a couple of uses. Typically, the black electrode (the negative side) gets discolored faster or more.”
The Hidrex electrodes need to be regularly cleaned, which increases the electrical resistance and makes treatment less effective over time. Or, the plates may even need to be replaced if you start to notice pitting – small holes in the metal.
What’s worse: metal ions are released into the water during treatment, most likely entering into the skin as well. This is why traditional iontophoresis is not suitable for patients with metal allergies.
The Fischer uses state-of-the-art silicone-graphite electrodes. Metal-free and soft to the touch, our electrodes cover up to 33% more surface area during treatment. They’re also signifigantly more durable and won’t ever corrode. Again, no-metal.
If you’re looking to treat both hands and feet at the same time, you’ll have the purchase an additional accessory from Hidrex. The Fischer: Hands & Feet comes with everything you need.
