This high-coverage lip color by Yves Saint Laurent dresses your lips in full-coverage color and high-impact vinyl shine. Its diamond applicator allows for perfect lip contouring and helps color glide on evenly in just one stroke. How to use: Use the pointed applicator tip to create a dramatic cupid's bow. Start by pressing the tip onto each side of the bow to emphasize the shape. Then sweep the flat side of the applicator from each corner on the top and bottom to the middle again. It's a foolproof way to achieve a sharp, professional edge.
