If you're not yet a fan of the Yves Saint Laurent Fragrances & Beauty page on Facebook now might be a good time to click on that 'Like' button. The beauty brand is launching a product line exclusively for its devoted social network fans.

YSL - in collaboration with Pantone and Facebook - is launching a line of products, the first being a limited edition 'PANTONE Facebook' palettes that only 1.650 fans will be able to snap up soon (there is no date of launch, as yet), according to designtaxi.com.

Apparently the ‘Devoted to Fans’ product line is a way for the brand to 'have a complete and global vision of digital — to separate [the brand] from a completely internet-orientated vision and to really digitalise all points of contact,' according to YSL’s marketing and digital director Carla de Préval, in an interview with frenchweb.fr.
