Yves Saint Laurent is expanding its wildly successful pen-brush empire—which includes the Perfect Touch Foundation and Touché Eclat Highlighter—with the release of its newest make-up product, Touché Brillance Sparkling Touch for Lips.

With a little click on the end of the pen, your lips become dazzling and iridescent. Infused with mother of pearl, this sparkly, transparent color is a show-stopper. Your lips will instantly feel hydrated and silky. And thanks to the fabulously soft yet firm brush tip that we've grown to love, application is smooth and even. You can wear it alone or as a top coat over lipstick. For an added sensuous effect, dab a dot of Touché Brilliance at the center of the lips. Buy it here for $28, and it's available in 11 shades.
