Do you use foundation all over your face or to cover any imaginable flaw, from wrinkles to blemishes? If so, Laura Mercier is here to tell you that you're making a mucho makeup mistake. Read on to learn the dos and don'ts of foundation.

Dos

• Do use foundation to even out your skin tone. Applied properly, foundation will help your skin look consistent in color and smooth.
• Do apply foundation only "here and there," just where your skin appears red or uneven in color.
• Do apply foundation by dabbing a bit on key areas and blending it with a damp sponge in a downward and outward motion.

Don'ts

• Don't cover your entire face with foundation like a mask.
• Don't use foundation to cover blemishes. Pimples are oily and slick, so foundation will slide off.
• Don't use foundation to cover wrinkles. It'll sink into the wrinkle, making it look deeper.
