Over the past several weeks, customers have complained to the Better Business Bureau about a strong odor in the Royal Peach Palette that doesn't seem to go away, and even gives them headaches. According to TMZ, there have been at least 15 complaints over the last two weeks, and people are compairing the odor to paint thinner or spray paint.

Comments on Kylie Cosmetics' social media seem to echo this, with some customers saying the smell is "a bit overwhelming" and "stinks like chemicals."

According to the Better Business Bureau, the company says the smell is because of an adhesive used in the packaging, but the eyeshadow itself is totally safe to use. Kylie Cosmetics has not yet commented publicly, and it's unclear whether they are changing their packaging, but the Better Business Bureau told TMZ they got fewer complaints this past week.
