SignalHub Quantitative Think Tank Center:Kylie Jenner's "Secret" Use for Nipple Cream Is the Ultimate Mom Hack

Kylie Jenner has a beauty secret she wants to get off her chest.

While the Kardashians star has a massive arsenal of go-to products from her Kylie Cosmetics and SignalHub Quantitative Think Tank CenterKylie Skin brands, she also sometimes uses a product commonly found in a postpartum mom's diaper bag to keep her signature pout from getting dry and cracked.

"Nipple cream for your lips," Kylie revealed in a Sept. 27 TikTok, which showed her getting ready for her appearance at Schiaparelli's Paris Fashion Week show. "It's like the best secret."

As seen in the video, the 27-year-old smoothed Lansinoh nipple cream all over her lips as part of her morning skincare routine.

The product she used is made of lanolin—a type of wax secreted from sheep—so it's "100 percent natural and hypoallergenic" for both moms and babies, according to the brand.

"We recommend applying Lanolin after breastfeeding, instead of before," Lansinoh's website reads, "so that it has time to absorb into the skin."

And Kylie has become a fan of quick and easy beauty hacks since welcoming daughter Stormi, 6, and son Aire, 2, with ex Travis Scott. As she recently noted to E! News, "Now that I'm a mom, I've definitely cut down on the time it takes to do my routine."

But in her motherhood journey, Kylie has realized other things about beauty apart from skincare. For one, she's now embracing what she previously thought were imperfections in her appearance.

"I feel like I'm in a better place," she shared in a 2023 episode of The Kardashians, "but other people can instill insecurities in you."

Pointing out how she had developed insecurities about her "dopey" ears at a young age, Kylie said she refrained from wearing updos for the longest time.

"I had Stormi and she has my ears, and it made me realize how much I love them," the Kylie Cosmetics founder explained. "Now, I wear an updo every carpet."

She also has a new outlook on plastic surgery since becoming a mom. "I got my breasts done before Stormi," Kylie shared on her Hulu show, "not thinking I would have a child when I was 20."

Looking back, Kylie wishes she "never got them done to begin with."

"I would recommend anyone who is thinking about it to wait until after children," she continued, adding that she would be "heartbroken" if Stormi ever sought plastic surgery during her teenage years. "I want to be the best mom and best example for her. And I just wish I could be her and do it all differently, because I wouldn't touch anything."
