Where is the recommended site for testing the microdermabrasion level?

• A. Inside of Wrist
• B. Inside of Elbow
• C. On the Neck
• D. On the Temple

Answer: (A)

When determining the microdermabrasion level, you want a patch of skin that reflects facial sensitivity but isn’t the face itself. The inside of the wrist fits this need perfectly because the skin there is thin and sensitive, so you can quickly notice irritation or a reaction to a chosen setting without risking the client’s facial skin. To test, apply a light pass of the device at a conservative setting on a small area of the inside wrist and monitor for 1–2 minutes for redness, stinging, or irritation. If no reaction occurs, you have a safe starting point for the facial treatment; otherwise, ease up to a milder level. Other sites can respond differently or pose more risk, so they’re not as reliable for this pre-test.
