Over its operating history, Nu Skin has faced various class-action lawsuits, shareholder complaints, and regulatory inquiries alleging deceptive income representations, unsubstantiated product health claims, and multi-level marketing compliance violations. Historical legal filings and regulatory actions from agencies like the Federal Trade Commission and state authorities focused on allegations that the enterprise or its distributors overstated potential earnings for independent representatives and promoted weight-loss or anti-aging supplements without adequate scientific substantiation. Additional investor lawsuits historically claimed losses stemming from regulatory investigations into overseas direct-selling subsidiaries and disclosure disputes.
