That’s right! Did you know that your body renews itself when you sleep, skin included? New skin cells grow to replace the ones that are dying a slow and painful death! Lack of sleep also causes the blood vessels around the delicate eye area to dilate, which causes dark circles! All the eye cream in the world will not take care of dark circles better than a good nights sleep! Try to aim for at least 7 hours. That being said, I am going to bed! Goodnight world!
