Class action lawsuit claims Eucerin misled lotion buyers with ‘natural’ label

Eucerin lotion class action lawsuit overview:

• Who: A consumer filed a class action lawsuit against Beiersdorf Inc.
• Why: The plaintiff claims Beiersdorf falsely advertises that its Eucerin lotions contain natural moisturizers.
• Where: The Eucerin class action lawsuit was filed in Illinois state court.

A new class action lawsuit alleges that Beiersdorf falsely advertises that its Eucerin lotions contain “natural moisturizing factors” when they actually contain synthetic moisturizers.

Plaintiff Christine Slowinski claims Beiersdorf violated Illinois consumer protection law by labeling its Intensive Repair and Advanced Repair lotions as being made with natural moisturizers, even though they contain lactic acid, glycine and other moisturizers manufactured in a laboratory.

Reasonable consumers understand the term “natural” to mean “found in nature and not involving anything made or done by people,” Slowinski argues in the Eucerin lotion class action lawsuit.

She claims Beiersdorf has been able to charge premium prices for the Eucerin lotions as a result of the allegedly false advertising.

Slowinski wants to represent a nationwide class of consumers who purchased the Eucerin lotions. She claims she would not have been able to identify the synthetic moisturizers in the lotions without “advanced chemical knowledge and investigation.”

Eucerin class action allegations detail synthetic moisturizing ingredients

Slowinski claims she purchased a Eucerin lotion at a Target store in Schaumburg, Illinois, in 2024, relying on the label’s claim that it contained “natural moisturizing factors”.

She says she did not know the product contained synthetic moisturizers when she bought it.

The lawsuit claims Beiersdorf uses manufactured, artificial lactic acid in its products by feeding a carbohydrate feedstock, such as glucose, to genetically engineered bacteria and collecting, refining and purifying the bacteria’s metabolic excretion.

The plaintiff further argues that Eucerin’s Advanced Repair lotions and creams contain sodium PCA, created through a two-step chemical process, and arginine HCL, which is formed through a chemical reaction involving hydrochloric acid. 

According to Slowinski, the Intensive Repair lotion also includes ozokerite, which is either heavily refined from naturally mined materials or chemically synthesized from petroleum-based sources.

She argues that Beiersdorf’s allegedly false advertising impaired her ability to choose the quality and products she decided to buy.

Meanwhile, several beauty companies, including Mielle Organics, Dr. Squatch and Charlotte Tilbury, are facing class action lawsuits over allegations of misleading advertising, product safety concerns and privacy violations affecting U.S. consumers.
