Sunscreen products and the aquatic environment

Only a small fraction of sunscreen products get into the water when you go swimming. Rapidly diluted in the water, it is found in extremely low concentrations in the environment. Marc Léonard, Head of L'Oréal’s Environmental Research, explains how he and his team of scientists are working to evaluate the impact of even very low concentrations on the aquatic environment. To do this, they have developed several methods in their laboratories to predict this impact.
