It’s all about security theater. Liquid explosives are a real threat, and mascara’s texture makes it suspicious. Imagine a terrorist trying to smuggle a bomb in a mascara wand. “Yes, officer, my lashes are just that dramatic.”
Even though mascara is mostly wax and pigment, the TSA isn’t taking chances. They treat it like toothpaste, gel, or love letters from your aunt’s jam. If it squishes, it’s a liquid.
Fun fact: in 2018, a woman tried to check a mascara tube that was just over the limit. She had to abandon it at security. Her lashes cried that day.
