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 excessive sweating, inflammation, and pain. By applying a mild electrical charge, the medication is pushed into the skin, allowing for targeted treatment without the need for injections. The procedure typically involves placing a gel or solution containing the medication on the skin, followed by the application of electrodes. Iontophoresis is considered a non-invasive and effective alternative to traditional methods, making it a popular choice for patients seeking relief from various ailments.
