“Keeping Up With the Kardashians” star Kylie Jenner has made a fortune from her lip kits, and she has always prided herself in making quality cosmetics that every girl will love.

Unfortunately, TMZ has reported that several customers have already filed complaints against her products, particularly her eye kits, because they caused chemical-induced headaches.

Around 15 people have filed complaints with the Better Business Bureau over the past two weeks, stating that Kylie’s Royal Peach Eyeshadow Palette smelled suspiciously of “chemicals and glue.” The customers even said the smell was similar to “spray paint” or “paint thinner.” One person who purchased the product said that the product smelled so foul that she had to put the whole package outside her house. Another customer claimed it gave her a “horrible headache.”

For now, Kylie Cosmetics has launched an investigation regarding these complaints, but the company insists the products are safe to use despite its foul smell.

Earlier, Jenner warned her fans not to patronize copycats of her products because these are dangerous to use. Given the success of her lip kits, it comes as no surprise that some have produced cheap versions of her make-up and are trying to pass them off as the real thing.

“I’ve come across this website called kyliecosmeticsoutlet.com. It looks exactly like mine, but it’s not. I want to be really, really clear and let you guys know that the only place to get my products is kyliecosmetics.com,” Jenner said in a video posted on her social media page. “Everywhere else is fake.”

“Make sure you guys check the URL because these other websites are selling fake product,” she clarified. “It might look exactly like mine, but it’s not mine.”

Jenner said her biggest concern is the ingredients they use in the fake products, which are “really, really dangerous.”
