Yves Saint Laurent Rouge Pur Couture The Slim Leather Matte Lipstick super-slim, highly pigmented matte lipstick with a long-lasting, comfortable matte formula. This lipstick uses an innovative square bullet that allows for easy application and creation of precise lines. The highly pigmented matte finish feels weightless and incredibly comfortable on the lips, while the non-drying, long-lasting matte formula helps avoid bleeding, cracking, or reapplying.
