Whether you're creating a full-on smoky eye or a soft daytime look, once you apply more than one shade of shadow, you should use a fluffy brush to blend the colors together. Try Tweezerman Brush iQ Blender Brush, $14, which is large yet has a slightly pointed tip that can reach the inner corners of your eyes. Use the brush simply to blend without any product, or use it to tone down your look with a dusting of light-colored shadow.

The best way to fake fuller lashes and defined eyes isn't with mascara or falsies, it's by tapping liner as close to your lash line as possible. A brush like Tweezerman Brush iQ Line Glider Brush, $12, helps you apply cake or gel liner exactly where you want it in a way that's soft and natural instead of overly sharp. Plus, the brush has a curved tip that matches the curve of the eye, making it a cinch to apply liner to both upper and lower lash lines.

Once you've finished your makeup, set it with translucent powder. Use a big, fluffy brush like Tweezerman Brush iQ Powder Brush, $33, which will pick up just the right amount of powder and distribute it evenly.

Focus the powder on your forehead, nose and chin -- anywhere you get shiny. Bonus: This brush feels incredibly silky. Keep one on your desk, and use it in place of a stress ball. Finish your look by gently tapping translucent powder under your eyes with the Contour Concealer Brush, $16, to prevent creasing.
