Have you noticed that you're left with a crisp line of foundation along your jaw after you apply makeup? It means you're not blending enough -- and you're also probably putting on too much foundation. Unless you have serious skin issues or are appearing on live TV, you don't need to go crazy with product. Focus your makeup toward the center of the face and wherever you have discoloration, and then gradually diffuse it as you reach your hairline and jawline.

The best way to achieve controlled foundation application is to use a brush like Tweezerman Brush iQ Foundation Brush, $16. The tapered shape makes it extremely precise -- perfect for tapping foundation from the center of the face outward. You'll never have to worry that it looks like you're wearing a foundation mask again.

There's nothing prettier than soft, perfectly contoured makeup. However, there's nothing worse than harsh streaks where subtle contour should be. After using the Tweezerman Brush iQ Mini Face Contour Brush Set, $25, to sculpt your face by shading underneath your cheekbones, reach for the Tweezerman Brush iQ Finishing Contour Brush, $29. It has two different types of fibers that allow it to blend makeup without moving it around. The result is defined, yet blurred -- kind of like your favorite Instagram filter.

You can also apply your foundation with the Blending Sponge in the Tweezerman Brush iQ Mini Face Contour Kit, or you can use it to blend out your freshly applied foundation for a more natural look. Simply run the sponge under water, and squeeze out the excess water in a towel. Then bounce the Blending Sponge over your face -- don't drag it -- for a seamless, streak-free finish.

When you look in the mirror circa 4 p.m., does the concealer under your eyes look like zebra stripes? If so, it's probably settling into fine lines. (If not, consider yourself one of the lucky few.) Fortunately, switching up the way you apply concealer can help with creasing, and using the right brush is the most important step. Tweezerman Brush iQ Pointed Concealer Brush, $12, gives you full coverage with minimal creasing because it evenly distributes concealer exactly where you need it. Focus the product on the dark circles or red spots, and tap -- don't drag -- the brush.

If your blush brush is too large, you'll end up looking flushed. If you blush brush is too small, you'll have tiny clown cheeks. A blush brush that's just right should cover the apples of your cheeks and have long bristles for blending color outward. The Tweezerman Brush iQ Blush Brush, $22, for example, is perfectly designed to deliver just the right amount of product exactly where you need it.

Tap the brush into powdered blush or press it into a cream formula, and then dust it over your cheeks. The application is subtle yet buildable, and the result is completely natural. Pro tip: For an airbrushed effect, use the side of the brush to apply your blush in an upward motion.

Brow pencil, while great for graphic brows, tends to look more artificial than brow powder. For arches that are soft and realistic, use powder and a brush like Tweezerman Brush iQ Brow Brush, $12. The bristles are angled and compact, so you can create tiny lines that mimic brow hairs.

Pick a powder that's slightly lighter than your brows to fill in underneath your arch. Then, use a shade lighter than your brows to hide holes and add thickness above your brows. The brow brush will give you plenty of control, and once you're finished no one will guess your brows aren't au naturel.
