Definition
Lip rouge is a cosmetic product used to add color to the lips, similar to lipstick. It's an older term and often refers to a creamier, more emollient form of lip color than a traditional lipstick. Think of it like the vintage version of modern lip products. It provides a softer, more diffused color, creating a natural flush. Lip rouge can also be used on the cheeks as a cream blush. It's typically applied with a finger or brush.
