Iontophoresis is a technique that uses a small electrical current to deliver medication through the skin. Think of it as a needle-free injection that uses electricity to push drugs into your body. It's non-invasive and relatively painless, though you might feel a tingling sensation. It's often used for treating conditions like excessive sweating (hyperhidrosis) or inflammation. The electrical current helps transport charged drug molecules through the skin barrier. It’s like a really high-tech patch.
