why do you have black bags under your eyes when you are tired?

Answer 1

the reason why is because this is a visual sign to show you and unfortunatly everyone else that YOU ARE lacking sleep. One key thing I learned in beauty school is drink tons of water too...flushes away toxins and keeps a healthy blood flow, which in turn keeps our skin healthy. I recomend using the good ole cucumber method, cold one. Cold reduces swelling. Also if your in a hurry..preperation H helps..after all it's made for reducing swelling. I know its kinda embarressing to buy but keep in mind it's not for you butt, it's for your eyes who cares. I'm not diggin the prep H gel because it flakes off so I'd stick to the cream. I use it and it helps. I lack sleep all the time it's my fault. Alcohol usage also increases the eyes to be puffy and swollen because it dehydrates you. Water is very key... Please get some rest this weekend.

Answer 2

Since our face consists of oil glands, it liberates oil when its exposed to air or sunlight.The process will be more rapid when we are under physical work.so during the whole day work we ger tired.So the oil produced by oil glands on face will get mixed by the tears gland of eyes.So we could see the black bags under our eyes when we are tired.

Answer 3

A lack of sleep or excessive tiredness can cause paleness of the skin, which again allows the blood underneath the skin to become more visible and appear more blue or darker.
