This study tested untested skin care lotions and creams on prison inmates over 30 days with repeated sunlamp exposures, developing a "patchwork" effect on their skin. It violated ethics by not allowing inmates to opt out or exercise free choice, and by offering payment that could coerce participation despite risks. The products were not tested first for safety. While the general public may have benefited from the knowledge, the data should not be used as the risks to inmates were unethical. It brought criticism on researchers and shed negative light on research. Guidelines were later proposed to better protect prisoner subjects.
