How to Choose the Right Iontophoresis Device:

A Patient’s Checklist

If you're living with hyperhidrosis, choosing the right treatment can feel overwhelming. But when it comes to choosing an iontophoresis device, having a clear, patient-first checklist can help you make an informed—and lasting—decision.

Iontophoresis is an FDA-cleared treatment that uses a mild electrical current and regular tap water to significantly reduce sweating. It works by pushing naturally occurring minerals (like calcium and magnesium) into the sweat ducts, essentially plugging the pores and preventing excess sweat from reaching the skin’s surface.

But not all devices are created equal. Here's what you need to know before choosing yours—and why thousands of patients turn to The Fischer iontophoresis device for safe, powerful, and consistent results.

The Checklist: What to Look for in an Iontophoresis Device

1. Choose an FDA-Cleared Iontophoresis Device

When you’re managing a medical condition like hyperhidrosis, FDA clearance matters. Look for an iontophoresis device that is clinically tested, hospital-grade, and built with patient safety in mind.
The Fischer is FDA-cleared and trusted by healthcare providers across the country.

2. Electrode Type: Avoid Metal-Based Iontophoresis Devices

Many iontophoresis systems still use metal electrodes, which can corrode over time, cause skin irritation, and require costly replacements. These issues not only reduce effectiveness but also increase long-term costs.

3. What Current Modes Should Your Iontophoresis Device Offer?
