Where should you test foundation on a client's skin for the best color match?

Testing foundation on the jawline is considered the best practice for achieving an accurate color match. This area is advantageous because it sits between the face and the neck, allowing you to assess how the foundation will blend with both skin tones. The jawline reflects the natural skin tone of the face while also harmonizing with the color of the neck.

Using this method helps ensure that the foundation looks seamless in natural light and appears consistent across both areas. Additionally, because the jawline can show undertones and depth similar to the rest of the face, it provides a clearer representation of how the foundation will ultimately appear when applied more broadly.

Other areas, such as the forehead, hand, and neck, may not provide a true representation of the client’s overall facial color match. The forehead can experience different lighting and oil production, the hand often has a different tone due to sun exposure, and the neck may not fully reflect the skin tone of the face. Therefore, testing on the jawline is the most reliable method for ensuring a foundation matches well with the client’s overall complexion.
