An Orthodox Jewish woman from Monsey, New York, has filed a lawsuit against Lancôme and its parent company, cosmetics giant L’Oréal, claiming that their “24-hour” foundation fades overnight.

Orthodox women can’t apply makeup on Shabbat and holidays, but can put it on the afternoon before and continue to wear it throughout the evening and next day, making long-lasting cosmetics an essential part of looking awesome for those occasions.

The suit by Rorie Weisberg claims that the Lancome foundation Teint Idole Ultra 24H “faded significantly” overnight, contrary to advertising, and said the company engaged in “deceptive acts and practices.” She is seeking an undisclosed sum and a “corrective advertising campaign” from the company, the New York Post reported on Wednesday.

“The 24-hour claim was central to plaintiff’s purchase decision,” her suit read, “as a long-lasting makeup assists with her dual objectives of compliance with religious law and enhancement to her natural appearance” — i.e., looking awesome.

Evidently, the suit is a preemptive strike, since Weisberg’s eldest son is having his bar mitzva in June and she was testing out makeup ahead of time for that event.

She’ll have a fight on her hands to prove her allegations: The suit “has no merit,” said a statement released by L’Oréal. “We will strenuously contest these allegations in court.”

No way this thing is getting cleared up before that kid’s bar mitzva.
