CeraVe’s parent company, L’Oréal, is facing a growing number of class-action lawsuits in the United States over allegations that certain acne treatment products can form benzene, a chemical classified as a known human carcinogen.
The legal actions have attracted widespread attention online, prompting concern among consumers who use CeraVe skincare products.
However, the lawsuits focus on a limited group of acne treatments containing benzoyl peroxide and do not involve the vast majority of CeraVe’s product range, including its popular moisturizers, lotions, and hydrating cleansers.
At least six class-action lawsuits have been filed against L’Oréal, with plaintiffs alleging that some over-the-counter acne products sold under the CeraVe brand may generate unsafe levels of benzene under certain storage conditions.
The lawsuits stem largely from findings published by independent testing laboratory Valisure, which raised concerns about the chemical stability of benzoyl peroxide, a common acne-fighting ingredient used in many dermatological products.
The lawsuits specifically target CeraVe acne treatments that contain benzoyl peroxide (BPO) as the active ingredient.
Among the products named in the legal complaints are CeraVe Acne Foaming Cream Cleanser (4% Benzoyl Peroxide) and CeraVe Acne Foaming Cream Wash (10% Benzoyl Peroxide)
Benzoyl peroxide has been used for decades as an effective treatment for acne because it helps kill acne-causing bacteria and reduce inflammation. It remains an FDA-approved ingredient and is widely recommended by dermatologists.
The lawsuits do not involve CeraVe’s standard moisturizers, hydrating facial cleansers, body lotions, or other skincare products that do not contain benzoyl peroxide.
The plaintiffs argue that benzoyl peroxide is chemically unstable and can break down into benzene under certain environmental conditions.
According to the complaints, exposure to elevated temperatures may accelerate this degradation process. The lawsuits claim that products stored in environments such as hot vehicles, warm shipping facilities, warehouses, or humid bathrooms could potentially generate benzene levels that exceed federal safety thresholds.
The plaintiffs further allege that L’Oréal either knew or should have known about the potential risk and failed to provide adequate warnings to consumers.
As a result, the lawsuits accuse the company of misleading consumers regarding the safety and stability of the products.
The legal filings seek damages and other remedies on behalf of consumers who purchased the affected acne treatments.
The controversy gained attention after Valisure, an independent laboratory known for testing pharmaceutical and consumer products, published findings suggesting that benzoyl peroxide products could generate benzene under certain conditions.
Valisure submitted a citizen petition to U.S. regulators and called for additional investigation into the safety of benzoyl peroxide formulations.
The laboratory argued that benzene formation could occur not only during storage but also as products age over time.
Those findings became the foundation for several lawsuits filed against manufacturers of benzoyl peroxide-based acne treatments, including L’Oréal.
However, the laboratory’s conclusions have not been universally accepted, and regulators conducted their own independent assessments.
While the lawsuits have generated significant media coverage and social media discussion, federal regulators have not reached the same conclusions alleged in the lawsuits.
The U.S. Food and Drug Administration (FDA) conducted independent testing of 95 benzoyl peroxide-containing acne products using validated scientific methods.
According to the agency, more than 90 percent of the products tested showed either undetectable or extremely low levels of benzene.
The FDA concluded that the overall risk to consumers appears to be very low under normal conditions of use.
Importantly, the agency has not issued a recall for CeraVe acne products.
Despite the growing number of lawsuits, no court has determined that CeraVe acne products are unsafe or that they caused cancer.
The allegations remain claims made by plaintiffs and have not been proven in court.
Legal experts note that class-action lawsuits often take years to resolve. Courts must evaluate scientific evidence, expert testimony, regulatory findings, and company records before reaching conclusions.
For now, the litigation remains ongoing.
Heat, direct sunlight, and excessive humidity can affect many cosmetic and pharmaceutical products, not just those containing benzoyl peroxide.
