Adam Levine's long list of jobs includes singer, songwriter, and perfumer, and now he's adding Proactiv+ spokesman to his résumé. But many of his fans don't know that Adam has dealt with acne since high school. "Acne doesn't care how old you are or how successful you are," Adam said. "Even though I'm a celebrity, I'm no different than anyone else. Acne just shows up and causes trouble. And it can mess with your confidence." Furthermore, in a behind-the-scenes video featuring Adam shooting a commercial for the brand, the star noted that everyone is insecure to some extent. "I'm not made of steel," he said, adding, "Things can bother me about my appearance all the time, and they do."
