A long thin face would be wider and fuller by applying a lighter foundation to the area of the?

To create the illusion of a wider and fuller appearance for a long thin face, applying a lighter foundation to the jawline is effective. This technique visually broadens the area and helps balance the overall facial proportions. By highlighting the jawline, it draws attention to this area, making it appear wider, which contrasts with the length of the face, resulting in a more harmonious look.

The other options focus on areas that might not significantly impact the width of the face in the same way. For instance, while applying lighter foundation to the forehead can add brightness and dimension, it doesn’t have the same direct effect on balancing the length of the face. Highlighting the cheekbones can enhance them but may also elongate the face rather than making it appear fuller. Similarly, applying lighter foundation on the nose tends to bring attention to its length rather than addressing the overall shape of the face.
