What should you know about iontophoresis at home?

During iontophoresis, the hands or feet sit in shallow water trays while a device sends a mild current through the water. Many people notice tingling rather than pain. The effect is temporary, so treatment generally begins with repeated sessions and later moves to a maintenance routine chosen for the person’s response.

Home treatment is different from simply soaking the skin. The device controls current delivery, and correct water depth, electrode placement, and skin condition affect comfort. Read the instructions for your particular [Iontophoresis Device](/technology/iontophoresis-device/) rather than copying another person’s settings.

Use the device on clean, intact skin. Remove jewellery, cover small cuts as directed, and keep the control unit away from splashes. Begin with the recommended intensity and increase only according to the instructions or advice from a clinician. Keep a simple record of sessions, sensations, and changes in sweating so the routine can be adjusted sensibly.

Moisturise after treatment if your skin becomes dry, but avoid applying products that the device instructions do not permit before a session. If home treatment is inconvenient or insufficient, professional [Iontophoresis](/treatments/laser-and-energy/iontophoresis/) or [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) may be discussed.

Pause treatment for burning, marked pain, blistering, persistent redness, or a shock-like sensation. Seek advice if sweating starts suddenly, affects the whole body, occurs during sleep, or comes with faintness, chest symptoms, fever, or unexplained weight change. Ask a clinician before use if you have an implanted electrical device, reduced sensation, open wounds, or a condition that makes electrical treatments unsuitable.

Is home iontophoresis suitable for my sweating pattern? Which areas can I treat, how should I protect my skin, and when should I expect to judge whether the routine is helping?
