Nu Skin products are legitimate, physical consumer goods that comply with standard cosmetic and dietary manufacturing safety regulations in the various countries where the enterprise operates. The company invests heavily in scientific research, clinical testing for its proprietary anti-aging formulations, and patented beauty device technologies like the ageLOC series. However, independent consumer advocates and beauty experts frequently note that while the products perform up to standard cosmetic expectations, their high retail pricing is heavily influenced by the multi-level marketing distribution structure through which they are sold.
