Jennifer Garner at Neutrogena's Sun Summit | Pictures

Jennifer Garner traveled to NYC to attend Neutrogena's Sun Summit today. She wore a purple Oscar de la Renta gown and talked to the audience about the damaging effects that the changing environment can have on our overall skin health. Jennifer has been a spokeswoman for Neutrogena since 2007 and has starred in a number of its commercials, but this is the first time she has attended an environmental awareness event as the brand's ambassador. This is just Jennifer's latest good deed after she and husband Ben Affleck cochaired the 10th annual Stuart House Benefit in LA over the weekend.
