Jennifer Garner: What I Hope My Kids Have Learned After Growing Up on My Lap in Makeup Chairs

Jennifer Garner has learned some important lessons about beauty over the course of her career, and she hopes to pass the “skin deep” mantra on to her three kids.

“I think it’s probably extra complicated when you literally were nursed in the makeup chair as an infant, and have grown up sitting in your mom’s lap while she got her makeup done your whole life,” the actress and Neutrogena brand ambassador tells PEOPLE.

“My kids know two versions of me: They know the version that I see in the mirror right now that looks crazy, and it’s what they see 90 percent of the time,” Garner reveals of son Samuel Garner, 7, plus daughters Seraphina Rose Elizabeth, 10, and Violet Anne, 13.

“Other times, they see a version of me that I never saw with my mom or anything, where I’m done up, my hair’s done, my makeup is done, so I wonder what that puts in [Violet’s] mind,” she shares. “Not to put words in her mouth, but I do wonder what it does to an adolescent brain.”

“I think whatever version of growing up they need to do around that, if they can come back to this in the end, we’re good to go,” Garner explains of the example she strives to set.

Garner’s kids are growing up fast — which, for Violet, means she’s starting to “explore and play with makeup” more as she becomes accustomed to her newly entered teenage years.

However, “She’s really smart about, ‘Okay, now I’m leaving the house, now I need to check with my mom because chances are she’s gonna make me take this lip off,’ ” says Garner. “Which, I do.”

“That’s kind of where we are with it,” adds the Alias alum of her oldest child. “It’s a process. Growing up is a process.”
