We gave you the skinny on this collaboration when word first came out, and now Khiels has released a campaign to accompany their Earth Day initiative. Continuing its collaboration with high profile creatives, Kiehl’s looks towards Pharrell Williams as the music producer takes part in the brand’s new açaí damage-protecting toning mist, an antioxidant-rich spray. Pharrell joins the likes of Jeff Koons, Malia Jones, and Juliann Moore with this new campaign, which donates a portion of the sales towards the Rainforest Alliance. The bottle is now available via Kiehl’s for $26 USD.
