You only need to know two things to get a perfect makeup base: contouring and highlight. These two tricks highlight your facial features and you do them with two concealers. One two shades darker than your skin tone and one two shades lighter. Here's how: If you're using pencil concealers, you have more control of the placement, which makes contouring easy. Just draw the lighter shade of concealer on the areas that naturally catch light, and use a darker one to shade in the areas that are naturally shaded. Then, blend with a buffing brush.
