Regular concealer can work wonders on dark circles, but when it comes to getting rid of puffy eyes, consider Estée Lauder Idealist Cooling Eye Illuminator, $64.

You apply this futuristic product with a ceramic-tip applicator that is made with a material that always feels cool on the skin. Plus, it contains skin care ingredients to tighten under-eye skin as well as 'triple-optic' technology (translation: a golden, opalescent shimmer) that reflects light from shadowy areas to make dark circles appear lighter. In trials, 90 percent of women saw a reduction in the look of dark circles and puffiness after just two weeks of use.
