Just a smidge of concealer under eyes helps brighten your outlook.
Step 1: CONCEAL. Look for a brightening concealer with a slight melon tone to correct the purplish hue of dark circles. My favorite is Benefit Erase Paste ($26), which comes in three skin-matching shades. I asked Benefit's Annie Ford Danielson for her top application tips.
Step 2: JUST A DAB. Your fingers are the best tool for applying concealer, Danielson says. She recommends patting the product on gently. "Less is more, so use the smallest amount possible to take away discoloration." Concealer that's too thick can bring focus to the area, which you don't want to do.
Step 3: SET AND GO. After the concealer sets, cover with your favorite foundation so you can't see where concealer starts and stops. "If you always apply concealer first, you'll notice you won't need as much makeup," Danielson says. Top with a light dusting of powder, and you're out the door.
