What is a "lip liner"?

A lip liner is a cosmetic tool used to define and shape the lips. It is a pencil-like product specifically designed for outlining the natural contours of the lips, creating a well-defined border, and preventing lipstick from feathering or bleeding. Lip liner is typically applied before lipstick or lip gloss to enhance the shape and size of the lips, providing a more precise and polished look. It can also be used to reshape the lips or correct any asymmetry. Lip liner comes in a range of shades to match various lipstick colors and can be blended or filled in to create a base for longer-lasting lip color. It is a versatile product that helps achieve a more defined and professional finish to the overall lip makeup.
