To use the elf contour palette, start by applying the lightest shades under the eyes and along the cheekbones to create a bright and healthy-looking complexion. Then, use the darker shades to contour the nose, cheekbones, and jawline. Blend well with a brush to create a natural look. Finally, apply the highlighter to the cheekbones, bridge of the nose, and forehead to create a glowing effect.
