Rethinking the use of population descriptors in dermatology trials and beyond: disentangling race and ethnicity from skin color

Importance: Race and ethnicity as population descriptors in research and clinical practice have often been a subject of debate, drawing heightened scrutiny in recent years. Criticism focuses on their oversimplification and misapplication, which fail to capture the complexity of human health and genetic diversity. There is growing recognition that these categories, rooted in outdated social constructs, do not accurately reflect biological differences. Observations: Historically, race and ethnicity have been used as proxies for genetic variation and skin color, despite the understanding that these constructs are not biologically defined. The Skin of Color Society’s second Meeting the Challenge Summit, attended by over 100 U.S. and international participants, highlighted several key themes: (1) the need for transparency in the rationale behind using population descriptors and decision-making processes; (2) recognizing the role of race and racism in dermatology; (3) exploring the intersection of dermatology, skin color, and cultural influences; (4) understanding the context of population descriptor usage; (5) developing improved, objective tools for classifying skin color; and (6) advancing research and creating guidelines. Conclusions and Relevance: There is an urgent need to reconsider the use of race and ethnicity as population descriptors in dermatology research. Current systems, which conflate social identity with biological markers, perpetuate health disparities and limit the accuracy of clinical data. Moving forward, more specific descriptors such as skin color, alongside socially determined factors, will be crucial in achieving meaningful diversity and inclusivity in clinical research.
