When is it recommended? If sweaty palms interfere with your work ▼ Severe palmar sweating can be embarrassing during handshakes, when holding paper, or when using sensitive electronic devices. For many people, palmar hyperhidrosis significantly limits daily activities. Iontophoresis is a method specifically developed and scientifically validated for palmar hyperhidrosis – significant improvement is generally observed after 1–3 weeks of regular treatment. If your feet sweat heavily – prevent shoe odor and fungal infections ▼ Heavy foot sweating can cause unpleasant odor and increase susceptibility to fungal infections. Sweating can be so intense that your foot slides in the slipper. The DermaDry Total works with a maximum current of 25 mA for foot treatment – reliably reducing moisture. Nightly maintenance sessions can be particularly effective. Do you have a large sweat stain under your arm? ▼ Axillary hyperhidrosis causes heavy soaking of clothing, which can be socially uncomfortable and lead to low self-confidence and social difficulties. The DermaDry Total operates at a lower current (8 mA) for underarm treatment – the device's specific electrodes ensure precise treatment. Although axillary treatment can take a bit longer, persistent users report positive results. Treatment based on medical recommendation ▼ If cosmetics or powders don't help (they rarely do), physicians should first recommend iontophoresis instead of more invasive and substantially more expensive treatments (botox or surgery). The DermaDry Total offers a non-invasive home alternative – and is cost-effective. Botulinum toxin injections need repeating every 4–6 months; surgery can have permanent side effects – iontophoresis, however, can be used long-term with minimal risk. Maintenance treatment – prevent recurrence ▼ Iontophoresis effects are not permanent – sweating may increase again after two to three months. After a course, switching to maintenance treatment is recommended: treat once or twice weekly. The DermaDry Total is ideal for long-term maintenance because it can be used anytime at home and treatments are not time-consuming. From adolescents to adults – age-independent use ▼ The manufacturer recommends the device from age 13. Simple reason: the treatment should be performed by someone who understands and cooperates with the process. For small children, medical consultation is required and a parent must be present during treatment. Iontophoresis can be effective for adolescents and adults alike, especially when hyperhidrosis causes psychological burden. Consult your physician about age suitability and a personalized protocol. How does iontophoresis work? Iontophoresis is a long-known, non-invasive procedure. During treatment the device conducts a mild electric current through tap water to the skin surface. This current influences the activity of the sweat glands. The exact mechanism is still under research, but scientific literature suggests several processes may play a role: temporary blockage of sweat gland ducts and raising the threshold for sweat-triggering stimuli. Automatic device functions: Polarity switching during treatment (no manual switching required) Safety current limiting Child lock function (3-second start) What can users expect? Iontophoresis effectiveness depends on individual factors and treatment regularity. Based on clinical studies: Mild tingling may be felt during initial treatments – this is normal With regular, protocol-based use, a large proportion of users experience significant improvement Randomized, controlled trials indicate that tap water iontophoresis can effectively reduce palmar sweating According to a systematic review, after 1–4 weeks of regular treatment a 30–90% reduction in sweating can be observed, which may persist for weeks–months with maintenance treatments Important: Results vary. Degree of improvement depends on sweat severity, treatment regularity and individual responsiveness. Iontophoresis does not replace medical consultation. Frequently asked questions What age can the device be used from? The manufacturer recommends the device from age 13. For younger users medical consultation is advised. Is the treatment painful? A mild tingling is felt during treatment. If uncomfortable, reduce the current. The device supports gradual current adjustment. How often should it be used? The detailed protocol is in the included manual. Generally, once daily for 2–3 weeks, then as maintenance once or twice weekly is recommended. If sweating increases, start a new intensive course. Can it be taken on trips? Allowed on planes? Yes, the device is compact and portable. For travel regulations, check the current airline rules regarding electronic devices. What happens if the water runs out? The device does not evaporate the water, so it won't "run out" during a 15–20 minute session. Treatment cannot proceed without water because the device has circuit detection. Without water it will not detect the proper circuit and will not start. How long until results are seen? Results vary and depend on sweat severity. Clinical studies report many users notice significant improvement after 2–3 weeks. Some see results sooner (1–2 weeks), others later (4+ weeks). How long does the effect of iontophoresis last? The effect of an iontophoresis course is not permanent. Generally sweating may increase again after a few weeks–months. The intensive course should then be repeated. Maintenance treatment is recommended: after a 2–3 week course, do not stop treatments completely but reduce frequency to 1–2 times weekly to maintain results longer. Overview of sweat treatment options There are several methods to treat hyperhidrosis. Consult your doctor to find the best solution for you. Method Characteristics Topical antiperspirants Can be creams, gels, powders, sprays. Easily accessible, require continuous use, may cause skin irritation Botulinum toxin injections Medical procedure, requires periodic repetition (usually every 4–6 months), fairly expensive Iontophoresis (DermaDry Total) Home-use, non-invasive, CE/FDA certified, requires maintenance treatments Anticholinergic medications Under medical supervision, may have side effects (dry mouth, vision disturbances) Surgical solutions (ETS) For severe cases, on medical advice; irreversible procedure. High risk of compensatory sweating. Video guide for using the DermaDry Total Watch videos about using the DermaDry iontophoresis device: User guide – in short 1 Preparation Fill the trays with lukewarm tap water (20–40°C). Check that there are no open wounds on the skin. Apply a thin layer of petroleum jelly to small abrasions. 2 Settings Select the treatment profile (palm/sole/underarm). Start at low current and gradually increase to a comfortable level. 3 Treatment Place your hands or feet in the trays. The device will automatically run the treatment with polarity switching in 15–20 minutes. 4 Finish Dry the skin and apply a moisturizing cream.
