Cosmetic products and dietary supplements marketed by Nu Skin do not undergo direct pre-market approval by the U.S. Food and Drug Administration, as federal regulations do not require standard cosmetics to secure individual agency approval prior to commercial sale. However, the enterprise is legally obligated to ensure that all personal care items, manufacturing facilities, and ingredients comply strictly with established federal safety standards, labeling requirements, and Good Manufacturing Practices. Dietary supplements must similarly adhere to safety regulations, though they are not evaluated by the agency to diagnose, treat, cure, or prevent any specific diseases.
