It’s no secret that women love getting beauty advice from celebrities. After all, looking great is part of their job, why wouldn’t we want some of their show-stopping tips?

Luckily for those aching for more insight, People.com recently spoke with a slew of Hollywood’s hottest ladies as they dished about their top beauty secrets.

It seems that Whitney Port and Kara DioGuardi, who starred on The City and American Idol, respectively, have more in common than appearing on hit reality shows. Both women confessed that it’s imperative to wash your face every night before bed.

According to Julianne Moore, gals should make it a point to protect their complexion.

“[It’s] not just putting on sunscreen every single day, but also just wearing a hat, walking on the shady side of the street,” the stunning actress told the news source. “That doesn’t mean you can’t be out in the sun, you just have to be really cautious about it.”

While loading up on skin care products may be the way to go, when it comes to makeup, Jennifer Garner swears that less is more.

“My top beauty secret would be don’t overdo it. For me, if you have a little concealer, a little mascara, a little blush, you’re good to go,” the 13 Going On 30 star told the website.
