Iontophoresis is a universally accepted method to treat mild to severe hyperhidrosis, approved by credible organizations like FDA, international hyperhidrosis society, and American Academy of Dermatology. The mechanism of action of this technique is probably through desensitization of nerve terminals of sweat glands without physiologic damage, via passing a mild current.
In comparison with Botulinum toxin (Botox) injection or surgery, iontophoresis is the only non-invasive yet fully effective method for treating excessive sweating. Also, it is uniquely a home-use therapy enabling the patient to perform the treatments individually at home, or share a device between many users.
As a result, Iontophoresis has been announced by many specialists as the best option for treating excessive sweating.
