In a campaign spearheaded by Rachel of Rabbit Write, lady bloggers everywhere have declared this No Makeup Week. Sound like a lot of pressure? Siobhan O'Connor and Alexandra Spunt, the intrepid co-authors of "No More Dirty Looks: The Truth About Your Beauty Products -- And the Ultimate Guide to Safe and Clean Cosmetics," say even going a day without making is a worthy social experiment (as long as, yes, you actually do leave the house).

If you're wondering what the point of going cold turkey on your cosmetics bag might be, Alexandra and Siobhan had this to say:

"A recent British study found that 70 percent of women wouldn't leave the house without their makeup tools. Half of those said they wore makeup 24/7, and 40 percent said they'd be embarrassed to be seen without makeup in front of friends and co-workers.

"We know it's a bit scary, but you'll be surprised -- it's kinda liberating, and may make you rethink how you apply makeup ... And once you've ditched it all, that kind of experiment won't be so intimidating."

Well, it all sounds very "liberating," for sure. It would be great to live in a world where some of us didn't feel compelled to spend 20-plus minutes in front of a well-lit mirror every morning so we felt presentable enough to brave our co-workers (especially given that most guys don't have to suffer the indignities of the perfect lid-line) ... And one where we didn't feel pressured to drop thousands of dollars a year on cosmetics to achieve "natural" beauty.

Want in? Here's how.

Sometime between now and Sunday, Sept. 27, go out barefaced. They're allowing a tiny bit of concealer for hiding zits, but you're stronger than that.

Just snap a picture of yourself doing it and email it here. They'll be posting the results next week, and they'll be back on Lemondrop to give us the exclusive scoop about how it all went down, so stay tuned.

Personally, we're predicting a mass breakup with pore-clogging foundation. (Enough already!) And the idea of letting natural beauty trump a more high-school-cheer-squad look is certainly refreshing. But the thought of no mascara and no powder is another matter for some of us entirely -- like those without visible eyelashes or with excessively shiny foreheads.
