6 Nighttime Habits That Make You Look Older

Why it's making you look older: Thanks to today's long-wear, budge-proof makeup formulas, "which require more than water and a gentle cleanser to remove," says Nazarian, you're probably going to bed with some makeup still on your face. That can lead to clogged pores, dull skin and accelerated skin aging, says Nazarian.

The fix: If you use long-lasting makeup formulas, start your cleansing process with a makeup-removing wipe or cloth (which will have ingredients that break down long-wear formulas better than a regular cleanser can. Look for ones that say "makeup-removing" on the packaging); then use your gentle cleanser to catch any traces the wipe left behind. The two-step combination is much more likely to get all of your makeup off before you hit the hay.
