Usage: 1. Begin by applying the concealer shade closest to your skin tone to conceal any blemishes, dark circles, or imperfections. 2. Use a lighter concealer shade to highlight areas such as the under-eye area, and bridge of the nose, forehead, and chin. 3. To contour, apply a darker shade along the hollows of the cheeks, jawline, and sides of the nose to sculpt and define your features. 4. Blend the concealer and contour shades seamlessly using a makeup sponge, brush, or fingertips for a natural-looking finish. 5. Set your makeup with translucent powder to enhance longevity. 6. Experiment with different combinations of shades to customize your look and achieve your desired level of coverage and definition.
