When you're tired or sick, your eyes are the first to show it. But you don't have to live with tired-looking eyes. Use these tricks to brighten up your eyes and give yourself a well-rested look. Instructions Get rid of puffy eyes. Keep a cucumber in your refrigerator to use on days when your eyes are puffy. Cut two slices of cucumber and place them over your eyes for 10 minutes. This will decrease any under-eye puffiness. Conceal under-eye circles. Many people have under-eye circles, and concealer is the only way to get rid of them. Apply the concealer to your under-eye areas after you have applied any foundation. Set the concealer with a loose powder. Curl your eyelashes. Curling your lashes opens up your eyes immediately. Curl them prior to applying your mascara. Be gentle, because your eyelashes are very delicate and can break easily. Shu Uemura makes an effective, high-quality eyelash curler. Use white eyeliner. Applying white eyeliner to your lower waterline brightens up your eyes and makes you appear more awake. Line your waterline with the white eyeliner prior to applying your mascara. Only a light lining is needed to brighten up your eyes. If you feel white eyeliner is too noticeable, use a cream- or even silver-colored eyeliner. Apply a coat of mascara. This further brightens up your eyes by giving your lashes color and volume. Black mascara provides a bolder and more dramatic look, as opposed to brown or black-brown. Remember, though, one of the most effective ways of combating tired-looking eyes: getting enough sleep. Source:eHOW
