A good night’s sleep can do wonders for our mood and general wellbeing, but it’s also an important part of a good skin care routine. “The less sleep you get, the more your body releases glucocorticoid, a steroid that can exacerbate breakouts,” Dr. Russak said. She also believes in changing your pillowcase at least once a week for clearer skin. A satin pillowcase is preferable because the weave reduces chaffing on the skin. If you have long hair, sleep with it pulled away from your face — your leave-in hair products might be aggravating your skin.
