Poll: What One Beauty Product Would You Choose?

Here's the situation: You're stranded on a desert island in the middle of the ocean and you can only have one beauty product (sunscreen's already a given). What would you choose? Go.

According to a Covergirl survey, 50 percent of women would choose mascara if they were forced to choose. But for many of us, it's hard to pick just one. We love our lipsticks, eyeliners, foundations, eyeshadows, and more importantly, our anti-aging creams.

But if you absolutely had to choose, what would it be? What beauty product could you not live without? Tell us what what you think in the *comments below.
