American singer/songwriter Cassadee Pope has been appointed as celebrity ambassador for Proactiv+, following in the footsteps of Olivia Munn, Adam Levine, Lily Aldridge and Julianne Hough.

Pope, who won the third series of US reality show The Voice, commented 'The stress of competition was obviously plaguing my skin and I sometimes spent more than 20 hours a day with make-up on my face. Thankfully, one of the make-up artists on set suggested I try Proactiv+. After just days of using the acne treatment system, my skin looked better and felt amazing. It has been a miracle for my skin'.
