Jennifer Garner Plays The Saxophone For Reese Witherspoon On Her Birthday

Jennifer Garner's got a new alias: skincare guru.

The 13 Going on 30 star recently offered her words of wisdom on aging and her refreshingly relatable approach to beauty.

"We should know how to feel and look as great as we can without any makeup," she told People in an interview published March 27. "I think these young kids that are following trends on TikTok, they're having fun, and that's awesome, but there's a difference between what's viral and what's vital."

That's why Jennifer is candid about the products that work for her skin at 51, including her go-to Neutrogena's Hydro Boost Water Cream. (She's an ambassador for the brand.)

"For women who are from 35 up, my favorite thing is to introduce them to hyaluronic acid," the Alias alum revealed. "The reason is, as we get older, we lose moisture in our skin. What it does is it binds moisture to the skin to make you dewy and plump."

Sharing her skincare insights is one of the ways she's leaving her (beauty) mark, as she noted it's "caused people to come up to me and say things like, 'I actually started wearing sunscreen because of something you said,' or, 'I didn't know what hyaluronic acid was.'"

As she put it, "It's empowering. Knowledge is power."

And although Jennifer sticks to the basics, her home is stocked with an array of makeup and skincare items.

"My vanity is very popular," she said, "so I can't have just one of anything. I cannot help but send people home with my favorite things."

Of course, the Last Thing He Told Me actress isn't the only star to share her foolproof secrets. Keep reading to see what other celebs have said about embracing their natural beauty.
