Question

Why does black spot form under our eyes if we don't sleep properly for consecutive days

Answer 1

lack of sleep tends to cause blood vessels under the skin to dilate creating a dark tint

Answer 2

Sleep is one of the most important things you can do for your skin,’ says dermatologist, Dr. Dennis Gross. 'During the day, your skin is in a protective state, warding off elements such as sun damage or oxidation, whereas at night, your skin goes into repair mode, regenerating new skin cells and cycling oxygen and nutrients. For the most part, dark under-eye circles are the result of lifestyle habits such as smoking, overindulging in alcohol, and not sleeping enough. Lack of sleep can put your body into flight or fight mode, which means your brain, like other vital organs, leaches every single molecule of oxygen it can from the blood, so a darker more deoxygenated blood flows through our veins to the other areas of the body.
