EOS, which makes a wildly popular lip balm touted by the likes of Kim Kardashian is being sued by customers who say they used the product and ended up a mess. 

Rachael Cronin has filed a class action lawsuit against the company, which sells its product in egg-shaped pods. Kim, Britney, and others are brand ambassadors.

The suit claims the product has produced a variety of bad reactions, including severe rashes, bleeding, blistering, cracking and loss of pigmentation. 

Cronin claims her experience was awful … she says within hours of applying the balm, her lips felt like sandpaper, so she applied it again. She claims her lips started cracking, flaking and bleeding, creating blisters and rashes which lasted 10 days.

The suit asks for damages and demands corrective advertising.
