Skin Aging Exposome in Skin of Color Populations: Review of the Literature

Abstract

BACKGROUND As life expectancy increases, the comorbidities related to aging require greater attention. Skin aging exposomes were only recently defined and need additional delineation, particularly in Skin of Color (SOC) populations. OBJECTIVE The primary objective is to shed the light and summarize the existing literature on skin aging exposome in SOC populations. MATERIALS AND METHODS We performed an extensive search in the PubMed and Google Scholar databases. We included peer-reviewed studies in SOC populations around the world regarding one or more of the skin aging exposome factors, and we grouped and organized the studies under each factor of the skin aging exposome. RESULTS Some environmental exposome factors are preventable or modifiable, for example, by applying broad-spectrum sunscreens with visible light protection, improving nutrition, and smoking cessation. Other factors such as air pollution will require more complex solutions. Our search revealed a paucity of references on skin aging exposome factors in SOC populations. CONCLUSION We identified the need for more dedicated studies in SOC populations to advance knowledge on skin aging exposome factors. This knowledge will provide a better understanding of approaches to minimize extrinsic skin aging in these populations.
