Supergoop Faces Lawsuit Claiming Its “100% Mineral” Sunscreens Contain Synthetic Ingredients

Case Overview: A California consumer filed a lawsuit claiming Supergoop falsely advertised its “100% mineral” sunscreens, alleging they contain synthetic and chemically processed ingredients.

Consumers Affected: California shoppers who purchased Supergoop mineral sunscreen products in the past four years.

Court: U.S. District Court for the Central District of California

A popular sunscreen and beauty brand sold at Sephora, Ulta, Amazon and Nordstrom is facing legal action that accuses it of misleading consumers about the ingredients in its mineral sunscreens.

A new proposed class action lawsuit accuses Supergoop of falsely advertising a wide range of products as “100% mineral” or “mineral” through labels, packaging and online marketing, even though the formulas allegedly contain non-mineral, synthetic and chemically processed ingredients. 

According to the complaint, the branding created the impression that every ingredient was mineral-based or natural, an assertion the shopper says is untrue.

Supergoop capitalized on consumers’ desire to avoid synthetic or chemically altered substances through a uniform nationwide marketing over several years that targeted both adults and children, she claims

Shopper Says Supergoop Misled Buyers With “100% Mineral” Claims

Pleasant Wayne, a California resident, filed the proposed class action lawsuit saying she bought Supergoop Mineral Mattescreen SPF 40 four times between the summer of 2023 and the summer of 2024.

She purchased the sunscreen at Ulta Beauty and Sephora stores in Los Angeles County, paying between $28 and $40 per product depending on the size.

Wayne says she relied on the “100% mineral” claims when deciding to buy the sunscreen and would not have made the purchases if she had known the full ingredient makeup.

The lawsuit claims she and other consumers paid premium prices based on advertising that did not reflect the true nature of the products, resulting in financial harm.

Complaint Alleges Products Contain Chemically Processed Ingredients

According to the class action lawsuit, the sunscreens and beauty products contain numerous ingredients that are not mineral-based or natural and, in some cases, are heavily processed or chemically modified. 

It argues that these processes fundamentally change the original source materials, making the final ingredients synthetic rather than mineral.

By continuing to market the products as “100% mineral,” the lawsuit claims Supergoop gained an unfair advantage over competitors while charging consumers $24 to $50 per item for products they believed met stricter standards than they actually did. 

Wayne says she formally notified the company of the alleged violations in August 2025, but the products continued to be sold with the same marketing.

Lawsuit Joins Wave Of Beauty And Skincare Mislabeling Cases

Supergoop is not alone in facing legal action over allegedly falsely advertising its sunscreen products. 

Makers of Think Baby sunscreen are accused of misleading parents with claims about total UV protection and being free of harmful chemicals and Hawaiian Tropic’s parent company, Edgewell Personal Care Brands, is being sued over allegations that one SPF 50 product only provides SPF 20 protection.

In the beauty sector, other lawsuits target claims around “natural,” “hypoallergenic,” and medical-style benefits across soaps, lotions and hair care products, including cases involving Valitic, Albertsons, Beiersdorf and Unilever.

Wayne is asking to represent all California consumers who purchased the challenged Supergoop products over the past four years. She is suing under California’s false advertising and unfair competition laws, seeking to stop the marketing practices, recover money consumers allegedly overpaid, and obtain interest, fees and costs.
