Iontophoresis is a medical technique that uses a small electric current to deliver medication through the skin. This method is often used to treat conditions like inflammation, pain, and excessive sweating. By applying a mild electrical charge, the medication is pushed into the deeper layers of the skin, enhancing its effectiveness. The procedure typically involves placing a medicated patch or solution on the skin, followed by the application of electrodes. Iontophoresis is considered a non-invasive alternative to injections, making it a popular choice for patients seeking relief without the discomfort of needles.
