A proposed class action lawsuit alleges that the maker of Huggies “Little Movers” disposable diapers, unbeknownst to consumers, materially changed the composition of the purportedly hypoallergenic products, leading to “scores” of reports of severe skin reactions.

The 19-page false advertising complaint contends that Huggies manufacturer Kimberly-Clark Corporation “materially altered the composition or construction” of the hypoallergenic diapers sometime in the past year without informing consumers or adequately updating product packaging.

According to the suit, parents have reported with the “reformulat[ed]” Huggies diapers “unusually strong, sudden, and severe skin reactions,” including rashes and chemical burns “inconsistent with what any reasonable consumer would expect” from a diaper advertised as hypoallergenic.

The case contends that the Huggies Little Movers diapers at issue—a recurring-purchase item, the filing stresses—are misrepresented and deceptively advertised by Kimberly-Clark.

“Nothing on the Product signaled to consumers that any chance in formulation had occurred,” the lawsuit emphasizes. “Nor did Defendant warn that the internal lining, materials, or other components had been altered in a manner that could affect the Product’s interaction with the skin.”

The class action lawsuit shares that reviews on the Huggies website indicate that consumers began to notice a “visible difference” in the diapers’ internal lining, including a new blue interior surface. Further, many of the reviews affirm that the consumer never had past issues with the same Huggies diapers, but that their infants had an adverse reaction after the supposed changes to the product’s formulation.

Because diapers are a recurring purchase for parents, the case emphasizes, consumers expect and rely on consistent formulation, unless the manufacturer indicates some kind of change. This is particularly relevant for a product touted hypoallergenic, as parents of infants with sensitive skin will actively seek the diapers out and typically avoid their non-hypoallergenic counterparts, the suit shares.

“By branding its Product as ‘hypoallergenic,’ Defendant misrepresents the nature of the Product and extracts a price premium from consumers,” the complaint argues.

In response to many negative consumer reviews, Huggies claimed that its diapers “cannot cause burns” because they are made of hypoallergenic materials, the case says. However, the company made no mention of any material or advertising changes, even in the light of reviews that mention the supposedly new blue liner, the case adds.

The plaintiff, a New York resident, purchased Huggies Little Movers hypoallergenic diapers on “numerous occasions” leading up to May 21, 2025. According to the complaint, the plaintiff’s child began to experience a sudden, unusual rash while wearing the product, which had never occurred in previous uses.

“By marketing the Product as hypoallergenic and failing to disclose a material change in its composition, Defendant engaged in a deceptive practice that misled reasonable consumers,” the suit asserts.

The Huggies Little Movers Diapers class action lawsuit looks to cover all consumers in the United States who purchased the Little Movers disposable diapers during the relevant time period.
