Love staying up late watching CSI? Then, it’s inevitable that you’ll get dark circles.

When you are tired, your whole body, including your circulatory system, goes into slow motion. You have less blood flowing through your skin, which gives you a pasty look and while lack of shut-eye doesn’t cause dark circles, not getting the recommended eight hours of sleep a night makes dark circles appear darker simply because your skin is paler.

This is what you can do as immediate fix. Slather on a cleanser or mask that contains skin-stimulating botanicals like ginseng or spearmint.

Then, camouflage under-eye shadows by dotting a concealer at the outer corners of the lower lids. Tap gently toward the inner corner of the eye, slowly blending in the concealer.
