Etichub confirms its commitment to scientific research applied to the cosmetic sector with the publication, in the international journal Cosmetics (MDPI), of a new article dedicated to the Exposure Intensity Index (EII), an innovative tool to measure skin exposure to air pollution.
The study “Exposure Intensity Index (EII): A New Tool to Assess the Pollution Exposure Level of the Skin” addresses the need for more effective methods to evaluate the impact of pollution on the skin, a topic of growing interest in the cosmetic field. While it is well known that smog, particulate matter, traffic, and smoking negatively affect skin health by accelerating premature aging and inflammation, validated methodologies to assess the real exposure of each individual are still lacking.
The Exposure Intensity Index: a new approach
The EII is an innovative index that integrates lifestyle habits with in vivo skin parameters. Through a structured model investigating residence, mobility, habits, smoking, and skin responses, it was possible to correlate urban or rural lifestyle with skin characteristics such as erythema index and stratum corneum hydration.
The results show that higher exposure to pollutants is associated with increased erythema, indicating a correlation between pollution exposure and skin redness phenomena.
Implications for the cosmetic sector
The EII represents a valuable methodology for cosmetic research and development, as it enables precise selection of subjects in antipollution clinical studies, strengthens efficacy claims, and provides replicable evaluation protocols.
This means relying on solid, transparent, and market-oriented testing procedures, in a context where the anti-pollution claim is increasingly becoming a priority for both consumers and brands.
With this research, Etichub further enriches its testing offering with ever more advanced methodologies, delivering high-value applied services rooted in scientific research and translated into concrete solutions for the cosmetic industry.
