NCT04016441

Brief Summary

This study seeks to determine what price consumers are willing to pay for a sunscreen product containing their ideal combination of attributes or qualities. This study will assess consumer preferences for various sunscreen qualities, as well as the relative contribution of each preference to the consumer's monetary valuation of a complete sunscreen product. The hypothesis is that respondents' willingness to pay for each sunscreen attribute will vary by demographic characteristics, especially self-identified race and socioeconomic class
