Testing for foundation match on the jawline is best for determining the perfect shade and undertones for your skin. The jawline is closer to your face and is less affected by sun exposure, making it the most accurate representation of your skin tone. Choosing to test on the wrist, neck, or arm may result in a mismatched foundation color as these areas are typically darker or lighter than the face due to differences in sun exposure and pigmentation.
