What it is: A superslim, full-coverage lipstick that provides Yves Saint Laurent's most luxurious, ultra-full, long-lasting matte finish yet.

What it does: Available in couture-inspired shades developed for every skin tone by creative director Tom Pecheux, this lipstick saturates your lips in ultra-rich, highly pigmented matte color that feels weightless and incredibly comfortable on your lips. The nondrying, creamy formula glides on effortlessly and stays put all day so you don't have to worry about bleeding, cracking or reapplying. It features a couture slim square bullet design inspired by the iconic designs of the brand's couture house.

How to use: Start by bringing the bullet up by 1/2-inch. For a natural lip contour, use the high point of the square bullet to line the cupid's bow, starting at the center of your lips and moving out. Then, fill in the bottom lip by laying the bullet on one of its sides. The square bullet allows application with clean precision and control. If you prefer, you can use a lip liner for precision instead.
