Ioniläpäisyydessä

Ioniläpäisyydessä, known in English as iontophoresis or ionto-therapy, is a therapeutic technique that uses a low-level electrical current to deliver charged ions into the skin. This process is commonly employed for both medical and cosmetic purposes. In medical applications, iontophoresis is used to treat conditions such as hyperhidrosis (excessive sweating), certain skin diseases, and to deliver anti-inflammatory drugs transdermally without needles. The electrical current facilitates the movement of ions, which are charged atoms or molecules, from a solution into the body.

The effectiveness of iontophoresis relies on the principle that like charges repel and opposite charges attract. In a typical treatment, a medicated solution or a saline solution is applied to the skin, and electrodes are placed over the treatment area. The electrodes are connected to a low-voltage direct current (DC) generator. If a drug is positively charged, it will be placed in the anode (positive electrode) compartment, and if it is negatively charged, it will be placed in the cathode (negative electrode) compartment. The current then drives the charged drug ions into the underlying tissues.

For hyperhidrosis, particularly of the hands and feet, tap water is often used, and the electrical current helps to block sweat gland activity. While generally considered safe when administered by trained professionals, potential side effects can include skin irritation, redness, or a tingling sensation. The duration and intensity of the current are carefully controlled to optimize therapeutic outcomes and minimize discomfort. Iontophoresis has become a valuable non-invasive treatment option for various dermatological and medical conditions.
