The Hidrex GS400 Iontophoresis Machine is designed for professional grade home based treatments against Hyperhidrosis, or as more simply known, excessive sweating. The high quality system is direct current and applies power to the patient 100% of the current cycle without a power pause.

The Hidrex GS400 Iontophoresis machine comes with all equipment needed to perform treatments on the hands and or the feet. The GS400 is compatible with other Hidrex accessories but we only recommend the pulsed current PSP1000 for underarms, face and torso. Treating the hands with a direct current machine is possible but pulsed current machines will permit higher power levels, resulting in better responses and shorter treatment times overall.


Iontophoresis therapy is an extremely successful treatment, but requires correct usage and the very best support available and not all patients will respond. Our unique level of FREE lifetime customer telephone, email, web and video support will ensure the best results and help you to normalise your sweat levels. If it fails to solve your sweat problem, we provide an 8 week money back guarantee*. In addition to our money back offer, the unit is provided with a manufacturer’s two year warranty. Please see our ‘guarantee and warranty’ section for more information.

A prescription from your GP is not required to undergo iontophoresis.
