Which area is specified for a thermal sensitivity test in the material?

• A. Inside of the wrist or ankle
• B. On the lips
• C. On the ear
• D. On the foot sole

Answer: (A)

A thermal sensitivity test checks how a client’s skin responds to the heat of wax before treating a larger area. The inside of the wrist or ankle is ideal because it has accessible, relatively thin skin that shows reactions clearly without involving delicate mucous membranes. Testing there lets you gauge whether the wax temperature is safe and whether any irritation or redness occurs, helping prevent burns on bigger areas. Areas like the lips or ears are too delicate and can react unpredictably, while the foot sole has thicker skin that may mask sensitivity, making it a poor predictor of how the skin will respond during a full wax treatment.
