EOS lip balm was made very popular as Kim Kardashian, Britney and Miley Cyrus all became brand ambassadors over the past year.

But it seems the lip company has a lot to answer now as customers have been experiencing very bad reactions. 

One woman, named Rachel Cronin has filed a lawsuit against the company after the product had "produced a panoply of bad reactions, including severe rashes, blistering, cracking and loss of pigmentation," reports TMZ.

Rachel said that within hours of applying the balm, her lips felt like sandpaper, and as she applied more they started to crack, flake and bleed, creating blisters and rashers that lasted nearly ten days.

TMZ tried to get a statement from the brand, but EOS decided not to reply. It might be time to put the egg-shaped pod away, so!
