Word of advice: Never take a snooze with a face full of makeup on. Likely, it's not the first time you've heard the age-old adage, but it’s important to understand why getting a wee bit lazy can have lasting effects. To get more details about the subject, I dialed up Melanie Palm, MD, MBA.

“Sleep is a restorative time for the skin, and if oil glands and pores are blocked by the day’s makeup remains, the results can be disastrous,” Palm tells InStyle. “Makeup products left on the skin do not allow skin to properly shed, and the makeup, old skin cells and environmental pollutants can accumulate on your pillow.” That said, it’s crucial to lock-down a nightly face washing routine to avoid skin mishaps like clogged pores, blackheads, inflammatory acne, and flaky, red, irritated skin (ouch) that could result from wearing makeup overnight.

Apparently, there are also differences between sleeping with face or eye makeup on. For face makeup side effects, see above. However, mascara and eyeliner come with different pitfalls. “Sleeping with eye makeup on puts a patient at risk for corneal abrasions (due to particles irritating the surface of the eye), and inflammation around the delicate tissue of the eye,” Palm says. “Inflammation around the eye can cause eye infections, irritation and clogging of glands around the eyelash line as well as eyelid redness and irritation.”

We get it: After a night of too many cocktails or long day of meetings, falling asleep with your makeup on can seem downright natural. If you can’t quite get your hands on your trusty makeup-removing formula before hitting the pillow, it’s crucial that you make your morning skin care routine a high priority upon waking up. “Use warm (not hot) water to loosen caked-on makeup to gently open pores of the skin,” Palm says.” If your skin is not sensitive, this would be a great opportunity to use an ultrasonic cleansing brush to ensure thorough cleansing to remove debris from the skin’s surface and pores.”
