The process that allows an acidic solution to enter the skin when assisted by direct current and the positive pole of an electrode is called which of the following?

• A. Desincrustation
• B. Cataphoresis
• C. Anaphoresis
• D. Fulguration

Answer: (B)

Iontophoresis uses direct current to push charged ions from a solution into the skin. When an acidic solution is used and the positive pole (the anode) is the active electrode, the acidic ions are driven into the skin by the current. This specific process is cataphoresis. It’s the term that describes delivering an acidic solution into the skin under the influence of the positive electrode. Desincrustation, by contrast, involves an alkaline solution and a different polarity to soften sebum. Anaphoresis refers to moving other types of solutions under a different polarity, and fulguration is a cauterizing/burning technique, not about ion delivery.
