If you've been skimping on sleep lately (we know we shouldn't, but sometimes we're guilty), you may notice that your skin has lost its usual brightness and luster. To make the gray go away, squeeze some fresh lemon juice onto a cotton pad and apply to skin.

"Lemon juice is an acid, so it can act as a toner for dull skin," says Dr. Sobel. "It has exfoliating properties, so it can help brighten the look of the skin.
