Which electrode creates a germicidal effect and is used in circular, gliding motions across the face?

• A. Spiral
• B. Mushroom
• C. Sparking
• D. Plate

Answer: (B)

The germicidal effect in high-frequency facial treatments comes from the mushroom-shaped electrode. Its rounded head makes it easy to contact the skin evenly, and the glass electrode inside allows the current to ionize the gas, producing ozone and a mild antiseptic action. Because the head is smooth and broad, you can move it in circular, gliding motions across the face, distributing the germicidal effect evenly and reducing the chance of concentrating energy in one spot. The other shapes are designed for different purposes: a spiral head for more targeted or vigorous stimulation, sparking electrodes for localized micro-sparks, and plate electrodes for broader, flat-area treatment. But for a germicidal effect applied with smooth circular motions, the mushroom electrode is the best fit.
