Nu Skin Enterprises, Inc.

Nu Skin Enterprises develops and sells cosmetic and pharmaceutical products, including anti-aging skincare and nutritional supplements, through a direct selling model. The company conducts animal testing as part of its product development and regulatory compliance processes. According to Cruelty Free Investors, Nu Skin is listed for conducting pre-clinical studies of its drugs on animals to assess safety and efficacy.

While Nu Skin states it does not test its cosmetic products on animals unless mandated by law, its overall business model includes pharmaceutical development that relies on animal testing. The company has also been subject to FDA warning letters regarding current good manufacturing practice (CGMP) violations, indicating regulatory oversight of its drug products, a category that typically requires animal data for approval. A 2013 Proposition 65 settlement for failure to provide warnings suggests past compliance issues with product safety regulations.
