5. Beauty Sleep

You need around 8 hours of sleep. People who follow this rule boast the best skin. Let your whole body have a good rest. Your skin also gets tired and needs to restore. After a sleepless night you will definitely have dark under eye circles. So our advice is: get used to going to bed between 10 p.m. and 12 a.m. To make your sleep deeper, drink some calming herbal tea or take a warm shower.
