How Does Iontophoresis Work ?

How does iontophoresis stop hyperhidrosis of the palms and feet? Researchers at the Department of Dermatology, Aichi Medical University School of Medicine, Nagakute, Aichi, Japan investigated the mechanism of action of iontophoresis and found that  hyperhidrosis patients have significantly higher perspiration volume and sodium concentration than healthy controls. Looking at changes with iontophoresis over time, the researchers led by Dr. Oshima found that there was a significant decrease in perspiration volume and sodium concentration after six iontophoresis treatments. These findings are helpful in targeting localized treatment modalities for patients with hyperhidrosis.
