What Actually Happened: I forged ahead against dermatological advice (and my better judgment) and swiped on another coat of foundation (I chose one with SPF 15 so that I didn't feel too awful about not applying sunscreen in the morning), mascara, eye shadow and lip gloss on the last day of the experiment. Not only did my skin look crazy-shiny by midday, my foundation started to pill around my nose. What's more, my lashes felt really dry and my eyes started to itch. I had dinner plans with friends that night, so I decided to take off my makeup in my office bathroom before leaving work. I was officially done with the experiment and was excited about getting back to living my makeup-free life.

I'll be real: There are still going to be days when I pass out in bed without washing my face -- and luckily, I now know that if it happens occasionally, the results won't be that awful. Of course, washing your face is always the better option than not doing it. But if you can't summon the energy to use face wash and water, cleansing wipes are a great option, says Marcbein. My faves are Yes to Blueberries Brightening Facial Wipes, $5.99 (and here are some other top-rated face wipes to try). Now if only I could get myself to wash my makeup-stained pillowcase.
