What should you know about galvanic iontophoresis?

The term galvanic refers to the steady direct current supplied by the device. During a session, the skin contacts water and the current travels across the treatment area. The exact biological effect is not fully predictable for every person, but sweat production may lessen for a time. The approach is most commonly discussed for excessive sweating of the hands or feet; treatment of the face or other sensitive sites needs extra caution.

Read the device directions before connecting the electrodes, remove jewellery, and cover small cuts only as the instructions allow. Never improvise electrode placement or increase the current to speed results. Keep the session within the recommended time and stop for sharp pain, burning, blistering, or persistent irritation. A clinician can review medicines, implanted electrical devices, pregnancy, skin conditions, and the reason for sweating before you begin. More background is available under [Iontophoresis](/treatments/laser-and-energy/iontophoresis/).

Get medical advice if sweating starts suddenly, affects the whole body, occurs with fever or weight change, or follows a new medicine. Seek urgent help for fainting, chest discomfort, breathing trouble, a significant burn, or a severe allergic reaction. Stop treatment and arrange review if the skin remains painful or damaged.

Ask which body areas are suitable, what current and session plan match your device, how to protect sensitive skin, and what improvement would count as meaningful. Discuss the [Iontophoresis Device](/technology/iontophoresis-device/) and alternatives, including [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/).
