They are loved by none other than Kim Kardashian, Britney Spears, Hillary Duff and Miley Cyrus. Yet these domes of supposed sheer goodness have landed in trouble.

The makers of EOS lip balm are now facing a class action lawsuit filed by Rachel Cronin on behalf of other plaintiffs. reports that Rachel Cronin claims to have suffered injuries and experienced dryness, cracking and bleeding on and around her lips within hours of using the “Summer Fruit” flavored balm. This then transformed into a severe rash and blistering, which lasted for a few days. Cronin had to resort to medical care to treat her condition.

Cronin posted some graphic pictures of her skin’s reaction to EOS’s Facebook page. Other customers followed suit. According to International Business times, her lawyer, Mark Geragos, is claiming damages and for EOS to alter its advertising pitch.

The brand endorsers for this egg-shaped balm were unaware of the adverse side effects caused to some of the consumers. EOS maintains that their lip balms are made of standard products like natural conditioning oil, moisturising shea butter and vitamins C and E reports International business Times.

EOS has responded to the lawsuit with a statement that says, “We firmly believe this lawsuit is without merit. Our products are made with the highest quality ingredients and meet or exceeds all safety and quality standards set out by our industry and validated by rigorous testing conducted by an independent lab. 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 time to share their experiences with us.”

PerthNow elucidates that EOS products do not retail in Australia. They are very popular in the United States, selling at US $3.29. All major supermarkets and chemist chain stores stock them.

EOS, which stands for Evolution of Smooth is an egg-like sphere that holds the lip-balm. One twist it open like the Kinder Surprise.
