For those of you headed to warmer climes (either for the holidays or for your sanity), there's only one stressor in the way of your daiquiri: TSA requirements. Airport security dictates that all liquid, cream, or gel beauty products must be in a container that is 3.4 ounces or fewer, and that all of said products fit in a quart-size bag. Beauty addicts, we feel your pain. Sure, you know about face wipes and powder foundation, but what about sunscreen, toothpaste, or mascara? We've found the most effective dry beauty products to stash in your travel kit, so the only reason TSA will stop you is to ask what (liquid-free!) nail polish you're wearing.
