It is pretty much agreed that Yves Saint Laurent’s Touche Èclat is the concealer to beat all—and this year, Touche Èclat is turning 20 years old! You can celebrate this anniversary along with Yves Saint Laurent by picking up a limited edition Celebration Edition Pen, which boasts engraved rings along the surface of the gold casing that are inspired by the Byzantine artwork seen in Yves Saint Laurent’s cruise 2011 collection. Whether you use it to conceal those dark circles under your eyes or even out your skin tone after a long weekend, one thing is certain: once you have used Touche Èclat, you’ll never look back. With that, head to Nordstrom to pick up your limited edition Celebration Edition Pen. Each pen retails for $45 and there are five shades to choose from.
