Just months after Jennifer Garner welcomed her second baby, she's taken on the role of Neutrogena ambassador, revealing to ET her hair and skin care tips.

"It's never too early to use eye cream," Jennifer, 36, advised.

The actress is the new spokesperson for the Neutrogena Triple Renewal hair care line and she was excited to participate in her first hair flip during the commercial shoot. "Hair, it turns out, is very entertaining."

Jennifer is costarring alongside Matthew McConaughey in the new romantic comedy 'Ghosts of Girlfriends Past', coming to theaters May 1.
