The phrase comes from Maybelline cosmetics advertising, where the full slogan is Maybe she's born with it, maybe it's Maybelline. Used in television and print campaigns, it suggested makeup could look natural rather than obvious. Over time the first half alone became a standalone catchphrase online, quoted whenever someone looks put together without visible effort. Its advertising polish is part of the joke, so creators reuse it for beauty edits, character entrances and ironic glamour moments long after the original campaigns.
