Kristin Cavallari says she doesn't wash her makeup sponges because she thinks they work better when they're 'not clean'

• Kristin Cavallari recently spoke with Glamour about skin care, beauty standards, and more.
• She said she doesn't wash her makeup sponges often because she thinks they work better dirty.

After nearly two decades on TV, Kristin Cavallari knows a thing or two about makeup. But, like many of us, she doesn't follow every beauty rule out there.

The "Very Cavallari" star recently spoke with Glamour about beauty standards, her skin-care routine, and more. When asked if there are any beauty rules that she thinks are "B.S.," Cavallari said she isn't convinced that you need to wash makeup sponges as frequently as recommended.

"The beauty blender face sponges - obviously we're supposed to wash those frequently, but I don't really wash mine that often because I actually think that when it's not clean, it helps blend better," she told the publication. "Maybe that's disgusting, but ..."

Experts previously told Insider that you should wash your makeup tools approximately once per week. Sometimes, it's also recommended to sanitize your actual makeup as well.

Though the Uncommon James founder didn't specify exactly how often or rarely she washes her sponges, it's likely that Cavallari's tools aren't all that dirty to begin with.

After all, she told Glamour that she prefers "the no-makeup makeup" trend, and looking both "natural" and "fresh."

"I wish that people would show more of their natural selves on Instagram," she said when asked what beauty standards she would change if possible. "Having kids too, it really scares me."

"I think it's hard as it is being a kid and growing up," she continued. "You're insecure, you're self-conscious, and then you throw all this social media on top of it and all of these unrealistic expectations and we're just setting our children up for failure. It's a really hard time to be growing up. I'm empathetic to all of the kids right now."
