Find a concealer that has a neutral, peach, or orange base.  We like Lancôme's Flash Retouche in Peche Éclat, $28.00, lancome.com.  It brightens and diffuses eyes for a radiant look.  Also, sweeps away flaws and signs of fatigue.

We love Yves Saint Laurent Touche Éclat in Luminous Toffee, $40, sephora.com. It works as an aluminizing pen that brings light and radiance to the skin, and erases any signs of fatigue. 

If your complexion falls into this category you will most likely need a concealer that addressed the blue undertone tones in your skin. Use an orange base like Make-up Designory's Deep Brown Corrector, $17, mudshop.com. It's a vivid orange color designed especially for dark skin tones.
