We have a tough question to ask you, one that we’ve been asking ourselves.

If you could only use 5 products—total—what would they be? Yep, it’s that childhood game, and we’re gearing up to make it a challenge, so think carefully: What would you take with you on a desert island?

Alexandra would probably take Rare Elements Conditioner, Tammy Fender Repair Balm, RMS lip-to-cheek in Rapture (though she’d shed a big tear for Ilia’s Bang Bang), Afterglow Concealer in Praline, and a good bar of soap. Or no soap—the ocean will clean her!—and her Laura Mercier waterproof mascara instead? Ugh, tough decisions.

Siobhan would take her Acure Shampoo (hydrating enough for her to forgo conditioner), Tata Harper’s Refreshing Cleanser, Laura Mercier Minerals (they’re clean!), 100% Pure Mascara and, like her pal, the Tammy Fender Repair Balm.

Now, tell us in the comments what you would take, and begin to mentally gear up for one of our most exciting (and challenging) challenges yet!
