Iontophoresis is a non-invasive treatment commonly used for palmar (hands) and plantar (feet) hyperhidrosis, and sometimes for underarms. The technique uses a mild electrical current passed through water to temporarily block sweat glands from releasing sweat.

How It Works:

• The affected area (hands, feet, or underarms with special pads) is placed in shallow trays filled with water.

• A gentle electrical current is applied, which temporarily disrupts the sweat gland activity in the treated zone.

• The exact mechanism isn’t fully understood, but it’s believed the current prevents sweat from being released through the skin’s surface.

Procedure:

• Each session lasts 20–40 minutes.

• Treatments are usually required 2–3 times per week initially, then reduced to maintenance sessions every 1–4 weeks depending on results.

• Performed either at a clinic or at home with a personal iontophoresis device.

Results & Duration:

• Noticeable sweat reduction often occurs after 6–10 sessions.

• Results are temporary and require ongoing maintenance treatments to sustain dryness.

Advantages:

• Non-surgical and drug-free

• Can be self-administered at home with a purchased device

• Effective for hands and feet, where other treatments are less practical

Limitations:

• Requires frequent and consistent sessions to maintain results

• Time-consuming and inconvenient for many patients

• Not suitable for patients with pacemakers, metal implants, or during pregnancy

Best Suited For:

• Patients with primary hand or foot hyperhidrosis

• Individuals who prefer a non-drug, non-surgical approach

• Those willing to commit to regular maintenance sessions
