Going to bed without removing your makeup

You may find it tempting to fall into bed after a busy day—or a late night on the town—without cleaning your face. But skipping a cleanser at night can lead to breakouts later.

During the day, environmental toxins (like dirt and pollution) build up on skin and invade pores, which can cause complexion problems, says Dr. Sadick. So don’t hit the sack before you wash. Use a good cleanser and save your skin. Keep a box of cleansing towelettes bedside for added convenience—simply swipe and sleep.
