Eyes may be the window to your soul, but they're also the window to your age, as this is the first place you'll probably see fine lines, not to mention those pesky dark circles. Using a dedicated eye cream is essential. It's specially formulated to be gentle on your delicate, dry, under-eye skin as it strengthens the area. To avoid calling attention to lines and under-eye circles, apply concealer and foundation to problem areas with a very light hand, and finish it with a little setting powder -- this will keep the makeup from settling into lines and making them look deeper than they are.
