Yes, under the TSA's 3-1-1 rule (and similar international standards), any makeup that is in the form of a liquid, gel, aerosol, cream, or paste must be treated as a liquid. This includes common items like liquid foundation, mascara, lip gloss, eyeliner, concealer, and even creamy blushes or eyeshadows. These items must be in containers of 3.4 ounces (100ml) or less and must all fit inside a single, quart-sized, clear plastic bag. Solid makeup—such as pressed powder, standard lipstick bullets, and eye pencils—does not count toward your liquid limit and can be carried freely in your makeup bag. In 2026, many airports have introduced advanced CT scanners that allow you to leave liquids inside your bag, but the 100ml volume limit per container still applies globally. To save space in your "liquid bag," many travelers switch to "solid" versions of their favorite products, like stick foundations or powder sunscreens, which are exempt from the liquid restrictions.
