A key feature that characterizes ethnic skin is skin color, which raises fundamental questions regarding whether deeply pigmented skin (black or brown) responds differently to chemical and environmental insults compared to fair skin. This inquiry extends to the efficacy of general skin care regimens, and whether certain racial groups face a different risk of developing skin diseases after exposure to similar challenges. The complexity of this issue necessitates a comprehensive approach, where the interpretation of pathophysiological phenomena must consider not only the anatomical and functional characteristics of various ethnic groups but also the influence of socioeconomic, hygienic, and nutritional factors.
