Using foundation to highlight and contour your face is a game changer in the world of makeup. This technique helps to define your features and gives your face a dimensional look. However, it can be tricky if you're not sure where to apply the foundation. The rule of thumb is to apply darker shades to the areas you would like to recede or hide, and lighter shades to areas you would like to highlight or bring forward. Remember that the key to any makeup look is blending. The harsh lines between your highlight and contour should not be visible. A makeup sponge or a foundation brush is recommended for achieving a seamless blend.
To highlight, you'd want to use a foundation that is one or two shades lighter than your skin tone. Areas to highlight include the center of your forehead, the bridge of your nose, your chin, the area under your eyes and below your cheekbones. This will bring these areas forward visually and give you a lifted appearance. When contouring, you'd be using a foundation that is one or two shades darker than your skin tone. The main areas to contour are the sides of your nose, your forehead (specifically near your hairline), your jawline, and right below your cheekbones. Contouring these areas will create shadows thus giving an illusion of a slimmer face and refined features.
When buying foundations for highlighting and contouring, you need to consider the undertone of your skin - whether it's cool, warm or neutral. This allows you to get a foundation that merges well with your skin tone, providing a natural look. Also, remember that the goal is to create depth and definition, not to contrast too much with your natural skin color. After applying your foundation, always set your makeup with a setting powder to ensure it stays in place and doesn’t crease. Lastly, practice makes perfect in the art of highlighting and contouring. Keep experimenting with shades and techniques till you find the one that suits you best.
