What effect does iontophoresis have on the skin?

• A. It weakens the skin barrier
• B. It introduces water-soluble products into the skin
• C. It removes dead skin cells
• D. It enhances pigmentation

Answer: (B)

Iontophoresis is a technique that utilizes a low-level electrical current to facilitate the movement of ionic substances across the skin barrier. This method enhances the absorption of water-soluble products into the skin by creating an electrochemical gradient, which helps the active ingredients penetrate more deeply than they would through conventional topical application. This process can effectively deliver various therapeutic agents, such as vitamins and medications, directly into the skin, making it a valuable tool in aesthetic and medical treatments. The ability to introduce these products enhances their efficacy, leading to improved outcomes in various skin conditions. In contrast, while iontophoresis may influence the skin's barrier function temporarily, its primary effect is to enhance product delivery, not to weaken the barrier or focus on exfoliation or pigmentation changes. Therefore, the correct answer highlights the core benefit of iontophoresis.
