Emma Roberts Campaigns for Neutrogena's Wave for Change

Plenty of celebs represent beauty companies. They apply moisturizer in the commercials and put on lipstick in the ads. Neutrogena, however, is taking it one step further -- not only do ambassadors like Miranda Cosgrove and Emma Roberts lend their faces to the brand, they also actively participate in Neutrogena's charity initiatives.

Now through August 31, they're helping to raise awareness for Wave for Change. The program is donating up to $250,000 to Global Giving to support school programs in underserved communities. Participating couldn't be easier -- all you have to do is watch the Wave for Change video on Neutrogena's Facebook page, and they'll donate a dollar for each view. You can also activate a recent Neutrogena purchase, and they'll donate another dollar.

We caught up with Emma Roberts who's been talking to teens about the charity. "I want them to know that you don't have to be older to make a difference," she says. "This campaign makes it so easy."
