Check any pro’s makeup kit, and Yves Saint Laurent‘s highlighting concealer pen is sure to be in there. For the last 2 decades (!), pro’s, celebrities and beauty enthusiasts have sworn by its light-reflecting and dark circle-erasing abilities (aka, you can quickly touch-up any dark spot or even skin tone). And to celebrate it’s 20th anniversary, YSL just launched a limited edition version of the pen in hammered-gold ($45), exclusively at Nordstrom. The pen case itself is inspired by Byzantine jewels from YSL’s 2011 cruise collection and the brand also launched 5 new shades to accompany it.
