EOS lip balm endorsed by famous artists like Kim Kardashian and Britney Spears is facing a class action case. A lawsuit was reportedly filed against the lip balm maker after the product allegedly caused negative effects to a user.

The complainant, Rachel Cronin, filed a lawsuit in California against EOS lip balm maker. In her affidavit, she stated that following several hours from using the lip balm for the first time, she felt her lips were like sandpaper—extremely dry and irritated. She then reapplied again to smoother her skin, only to find out that her lips started cracking, flaking and bleeding. The next day, blisters and rashes started sprouting all over her mouth, and manifestations lasted for 10 days.

Cronin, who is from Los Angeles, further claimed that after posting her photos on Facebook, there were several other people who claim to have the same experience. Her lawyer, Mark Geragos, said they will be gathering all individuals who have the same complaints. In addition to seeking damage, he is also asking the company to address the health issue that might have affected hundreds or even thousands more.

Meanwhile in a statement released by EOS, it claims that the class action lawsuit is without merit. In defense, it claims that its products are only made from the highest quality ingredients proven safe and approved by the FDA and Cosmetic Ingredient Review Board without warning labels, have complied with the standard set by the industry and have undergone rigorous clinical testing.

Furthermore, they stated that from the millions of pieces sold, the company has received 40 complaints so far that is only a 0.001% rate. Out of these customers, 35 agreed to get a replacement coupon, while the other five have unknown whereabouts.

"The health and well-being of our customers is our top priority and millions of satisfied customers use our products every day, many of whom take the time to share their experiences with us," EOS stated.
