The Laura Mercier Caviar Perfecting Lip Liner is designed to precisely define and shape the lips, offering a flawless base for any lip color application. Its creamy yet firm texture allows for smooth gliding, preventing feathering and extending the wear of your lipstick or gloss. Use this liner to outline the natural lip line or to carefully fill in the entire lip for enhanced color dimension and longevity. It ensures a polished, precise finish suitable for both everyday wear and more elaborate makeup looks.
