Ways to reduce exposure to chemical pollutants: the example of skincare and cosmetic products

Conference in french

Speakers: Sarah Lyon Caen, Claire Philippat, IAB, Grenoble.

Using fewer cosmetics and skincare products can quickly reduce exposure to several chemicals, including known or suspected endocrine disruptors, according to a study published in Environment International by researchers at the IAB. Conducted among approximately 100 student women, this study shows that reducing the number of cosmetics and skincare products used and switching to alternatives free of several compounds suspected of having adverse health effects (including methylparaben and certain phthalates) leads to a decrease in urinary concentrations of these substances in just five days. A decrease in the concentration of bisphenol A was also observed. This substance, classified by the European Union as “of very high concern,” is a proven endocrine disruptor and a suspected reproductive toxin. For the first time in this type of study, the researchers, in collaboration with the Grenoble-based GAEL laboratory, conducted a health impact assessment aimed at estimating the potential health and economic benefits of such a change in cosmetic routines at the population level.

This joint presentation will review the results of this study and highlight other ongoing initiatives aiming to identify strategies to limit exposure to chemical pollutants in the general population.
