What effect does a rotating brush produce?

• A. Electrical
• B. Mechanical
• C. Thermal
• D. Chemical

Answer: (B)

A rotating brush produces mechanical action. The rapid motion of the bristles physically agitates the skin, providing exfoliation and enhanced cleansing by lifting and dislodging oil, dirt, and dead skin cells. While the device is powered by electricity, the primary impact on the skin is the physical movement and friction—not heat or chemical changes. This mechanical action is what makes rotating brushes effective for cleansing and light exfoliation.
