To mark and promote the launch of its new Double Serum, Clarins aimed to strengthen the relationship with its female readers and to create a strong brand message for its new product. ELLE France offered Clarins high visibility and interactivity through a 360° campaign involving a beauty test for ELLE online visitors along with the creation of a promotional “mini-magazine”, advertisements and editorials on Europe 1 radio station to support the campaign, and a competition via social networks.
