Using a lip liner provides several advantages, particularly in defining the lip shape and preventing the lipstick from feathering. By outlining the lips with a lip liner, a more precise definition is achieved, which enhances the overall shape and gives the lips a fuller appearance. This is especially helpful when wearing bolder colors, as it prevents the color from bleeding outside the natural lip line, maintaining a clean and polished look throughout the day.

The other options suggest benefits that do not align with the primary function of a lip liner. While a matte effect can be achieved with certain lip products, lip liners primarily serve to define and prevent feathering rather than create texture. Adding color is a task more suited to lipsticks or glosses rather than lip liners, which usually come in neutral or similar shades to the lips. Hydration is not a function of lip liners either; rather, it's typically a benefit associated with lip balms or moisturizers. Thus, the defining and protective qualities of a lip liner make it a valuable tool in cosmetics.
