Which area is used to test the microdermabrasion level?

• A. Inside of Ankle
• B. Inside of Wrist
• C. On the Back of the Hand
• D. On the Forehead

Answer: (B)

Testing the microdermabrasion level relies on observing how the skin reacts to a chosen setting on a safe patch area. The inner wrist is used because its skin is thin and relatively sensitive, similar to facial skin. This makes reactions like redness or irritation easier to see quickly, so you can gauge whether the abrasive level is too strong or just right without risking the client’s facial skin. It’s also a convenient, clean spot you can easily inspect right away. Other sites aren’t as ideal for a reliable signal. The inside ankle can have different skin thickness and conditioning, which may not reflect facial response. The back of the hand varies more between individuals and isn’t as representative of facial skin. Testing on the forehead would mix with the actual treatment area and isn’t appropriate for calibrating the setting.
