If you don't have time to sit for 10 to 20 minutes with slices of cold, raw cucumber on your eyes, you can use makeup to conceal puffiness and draw attention away from the problem.
First, apply concealer around the entire eye area (lash line to brow bone, too). Next, set it with a light dusting of translucent powder. Then apply a dark liner to your upper lash line and add your favorite eyeshadow to your lids. Lastly, curl your lashes and apply mascara only to the upper lashes.
This look can be as dramatic or subdued as you like, depending on your choice of shades. But it's vital that you avoid lining or applying mascara to the lower lash line -- the point is to draw attention away from the undereye area.
Tip: After you apply the rest of your makeup, sweep a touch of blush across your lower eye area -- yes, over the bags. This also will help reduce the appearance of puffiness.
