A federal judge has refused to dismiss putative class actions alleging that L’Oreal made outlandish claims about its anti-wrinkle products, such as that they “boost the activity of genes” and “stimulate cell regeneration.”

U.S. District Judge William Martini let stand 24 of the 26 counts in a dozen cases centralized in New Jersey, In Re L’Oreal Wrinkle Cream Marketing and Sales Practices Litigation, finding the plaintiffs sufficiently alleged fraud and other wrongs.
