In what's possibly the lowest barrier to entry for a giveaway ever, Smashbox wants to pay you for your selfies—in makeup. Now, if the idea of winning free stuff didn’t get your blood moving, there’s even more incentive: For every selfie received (or .gif created in their nifty .gif generator), Smashbox will donate a product to Look Good Feel Better, a group that works to boost the self-image of women undergoing cancer treatment. Simply tag a photo on Instagram, Facebook, Twitter, or on Smashbox’s Shape Matters Hub with the hashtags #shapematters #sweeps. Heck, throw a #nofilter in there, too.
