9 Beauty Bag Travel Essentials, According to a Professional Packer

I'm diligent about applying sunscreen, especially in-flight. The sun's rays are significantly stronger when you're 35,000 feet in the air and can cause significant damage. This Supergoop spray ($12) refreshes and resets your makeup while giving it the extra protection it needs. I love it because it doesn't have a medicinal sunscreen smell and rehydrates my skin while in-flight.
