Trendy Mousse Sunscreens May Not Actually Work, FDA Warns

The US Food and Drug Administration warned that trendy whipped sunscreens made by Supergoop! and other manufacturers don’t comply with federal laws and may not work.

“Beware of sunscreen products in mousse form because they might not be effective,” the agency told consumers in a post on X after it sent warning letters to five companies. The FDA said regulations allow for marketing sunscreen products as lotions, creams, sticks, sprays and a number of other formulations, but the rules to date don’t allow for foam or mousse.
