Stepping out in support of an important issue, Jennifer Garner was on hand at the Neutrogena Sun Summit on Wednesday (March 13) in New York.

Donning a lovely purple Oscar de la Renta frock, the "Alias" actress posed on the arrivals carpet outside The Glass Houses before heading inside to get the latest scoop on sun protection.

The yearly get-together, which is sponsored by the popular skin care brand, explores the connection between climate change and the sun’s impact on skincare needs.

Ms. Garner has been a spokesperson for Neutrogena since 2007 and has been featured in a number of their commercials.
