Which sign warrants referral to a physician?

• A. A minor pimple
• B. Slight redness after cleansing
• C. Visible signs of skin infection such as redness, swelling, or discharge
• D. A mild itch

Answer: (C)

Recognize when medical evaluation is needed: signs of infection on the skin require referral to a physician. When you see visible redness, swelling, or discharge, those are indicators that an infection may be present and could worsen or spread with barbering procedures. It’s important to pause work on that area and guide the client toward professional medical assessment.

In contrast, a minor pimple, slight redness after cleansing, or a mild itch are typically non-infectious irritations or common skin variations that don’t automatically require a medical referral, especially if they don’t show spreading redness, warmth, swelling, or discharge. If any of those symptoms change—spreading redness, increasing swelling, warmth, or new discharge—then a medical evaluation becomes advisable.
