[Tap water iontophoresis].

Palmoplantar hyperhidrosis remains a challenging condition for dermatologists. Prior research has shown that conventional therapies often fail to provide long-term relief. No prior work had resolved the issue of long-term efficacy and safety. This gap motivated the exploration of alternative treatment methods. Established knowledge includes the role of eccrine glands in sweat production. However, the exact mechanisms of non-pharmacological interventions remain unclear. That uncertainty drove the need for a treatment that could target sweat glands without systemic side effects. This paper's contribution is the detailed analysis of a specific non-invasive method's application and effects.

The aim of this paper is to evaluate tap water iontophoresis as a treatment for hyperhidrosis. The specific problem is the lack of long-term, non-invasive treatment options for excessive sweating. This method was investigated due to its potential to interfere with sweat gland activity. The motivation is to provide a safe and effective alternative to current therapies. The study addresses the need for a treatment that avoids systemic absorption. The focus is on understanding the treatment's mechanism and optimal application. It also seeks to clarify contraindications and safety parameters. The goal is to guide clinical practice with evidence-based protocols.

The study analyzes the application of tap water iontophoresis for hyperhidrosis treatment. Treatments were performed using electrodes placed on affected areas. The process involves passing a low-level current through tap water. The current direction was adjusted during treatment cycles. The induction phase involved daily sessions until symptoms improved. Maintenance therapy was conducted weekly with alternating polarity. High-frequency pulsed direct current was used to minimize discomfort. The method also includes safety protocols to prevent skin irritation.

Tap water iontophoresis significantly reduced symptoms of palmoplantar hyperhidrosis. The treatment also extended symptom-free intervals in dyshidrotic palmar eczema. The most effective current was pulsed direct current at 5-10 kHz frequency. Side effects were minimal, limited to slight skin irritation. No long-term complications were reported with proper precautions. The treatment was well-tolerated in children and adults. Current direction adjustments improved treatment outcomes. The method showed no significant adverse effects when used as directed.

The authors propose that tap water iontophoresis disrupts eccrine gland function without systemic effects. The treatment is suitable for both palmoplantar and axillary hyperhidrosis. Pulsed direct current is better tolerated than continuous current. The method is safe when used with proper precautions. Contraindications include metallic implants and compromised skin barriers. Pregnant individuals should avoid this treatment due to lack of data. The authors suggest that this method can be integrated into standard care protocols. They emphasize the need for further studies on long-term outcomes.
