Exposure Intensity Index (EII): A New Tool to Assess the Pollution Exposure Level of the Skin
Year: 2025
Type: article
Study design: Observational Study
Abstract: Air pollution is known to affect skin health, but tools to objectively measure individual exposure based on skin responses are limited. This study introduces the Exposure Intensity Index (EII), a novel tool that correlates lifestyle-related pollution exposure with skin parameters. A panel of 250 women residing in Lombardy completed a detailed questionnaire on socio-demographic features and daily habits, from which an exposure score was derived. Non-invasive bioengineering techniques were used to assess skin parameters, focusing on inflammation-related signs. A positive correlation emerged between exposure scores and variations in specific skin parameters, suggesting a link between daily pollution exposure and skin alterations. The EII emerges as a preliminary exploratory approach to estimate environmental impact on the skin through its correlation with biophysical parameters. It may offer future value for subject selection in in vivo testing of antipollution cosmetic claims.
