NARS launched a Christmas limited-edition series on October 26 and invited celebrities @蔡依林, @WaackerAC雷曦, @石璐Atom, etc. in its promotion. A Double Eleven special gift box was put on sale on Tmall on October 21. The brand initiated an online discussion with rewards and an offline exhibition to achieve higher engagement and brand exposure. @DC大叔, @赵梦玥UU, @荒原君Sue, and other KOLs posted try-on photos and product reviews. Weibo hashtag #NARS54潮能天团# tracked over 80M views. Slightly over half of the KOLs in this campaign (61%) managed to achieve an engagement rate above their past 90-day average data. The KOL selection for this campaign is satisfactory and has room for improvement.
