Cashing in on the gossip over her ballooning lips, Kylie Jenner became Instagram's ultimate makeup queen after launching her sell-out range of beauty products, Kylie Cosmetics. But the newest addition to the 19-year-old's range, the "Kyshadow" eyeshadow palette, has left customers claiming the makeup is toxic.

The youngest Jenner may be used to the spotlight as a member of the Kardashian reality TV dynasty, and while her products have achieved sell-out success, it hasn't been without issues and complaints. So far, people have questioned the authenticity of her images, complained about poor customer service and accused her of repackaging old lip kits.

In an all new Kylie Cosmetics scandal, customers are complaining that the eyeshadow palettes have a toxic odour that causes headaches and have questioned the level of chemicals in the product.

Kylie Cosmetics has responded, claiming the cause of the toxic smell is the glue in the packaging, rather than the eyeshadow itself. While the eyeshadow is said to be safe to use, the product is still headache-inducing, according to customer claims.

While this may be another small shadow on her brand, undoubtedly the scandal will subside and her die-hard fans will still rush to buy her products in an effort to emulate her look, and so her immense fame and fortune will continue.
