Where should undertone on a client's skin be determined?

• A. Wrist
• B. Neck
• C. Cheek
• D. Forehead

Answer: (B)

Determining undertone means finding the underlying skin color that affects how makeup will look, not just the surface color. You want a part of the skin that shows that true color without being changed by sun, makeup, or hair. The neck is the best area for this because its color tends to be more consistent with the face and less affected by sun exposure or cosmetics than the forehead or cheeks. The wrists can be influenced by tanning or veins and don’t accurately reflect facial undertone, while the cheeks and forehead often show sun exposure or makeup color, which can mislead you about the undertone. Checking the neck (near the jawline) gives a reliable base for matching foundation and ensuring a natural blend.
