Kaia Gerber's Best Beauty Tip is 100% Free & Easy to Do

If you’re experimenting with beauty products and/or trying to figure out your look, Kaia Gerber has some excellent advice… and it’s absolutely, 100% free and easy to do.

The 15-year-old daughter of OG supermodel Cindy Crawford was just named the face of Marc Jacobs‘ new campaign for Daisy fragrance.

This is HUGE! So huge, in fact, she confessed to Coveteur that she didn’t tell anybody she knew about it until the pictures started coming out, because she was afraid it might go away.

Kaia, who joined her brother Presley Garber at the Daisy campaign launch event last weekend along with Sofia Carson, Lizzy Greene, Maddie Ziegler and Joey King (see pix in the gallery and more here), also revealed her biggest beauty secret.

“[My favorite trick I've learned on set] is learning to brush my eyebrows up,” she explains. “Not all the way to the side, but leaving them a little bit messy. I think it looks really cute, and young. That’s the thing now, full brows. And that’s the trick! To leave them full, because they never grow back. I’ve just left them.”
