Jennifer Garner  spent a girls' day at the beach in Santa Monica with her daughters, Violet and Seraphina, yesterday. She and Sera shared a laugh as they tried to avoid the waves during a dip in the water. Jen covered up from the sun in a wide-brimmed hat and long-sleeved denim shirt, which was appropriate attire since she's an ambassador to Neutrogena and an advocate for sunscreen protection. Jen followed her own advice after traveling to NYC just last month to speak out about the damaging effects of the changing environment at Neutrogena's Sun Summit .
The sandy afternoon wrapped up a busy weekend for Jen. Earlier Sunday, she and Violet also ran errands together, and on Saturday, the girls spent time with Ben Affleck  at the Brentwood Country Mart . Jen and Ben may have been all about family time, but they kicked off the weekend with a date night on Friday.
