Fatigued? Get up and move around! Stretch for about 10 minutes then drink a glass of cold water. Also, try eating a handful of nuts!
If your eyes look tired apply concealer or a light shimmer shadow to the inner corners of your eyes and under lower lashline.
Apply light colored eye shadow to hide tired eyes. Soft colors like a light pink or purple applied to the top lid will draw attention to the color instead of the darker circles under your eyes. Also, use a nude eye pencil and line your lower lid. This will help downplay any tired redness and will make the whites of your eyes pop. (totalbeauty.com)
