Valerie Michaut, Director: Alternative Methods & Reconstructed Skin

Would you like to know how at L’Oréal we ensure the safety of your favorite sunscreen? First, I take a sample of reconstructed skin … then I cover it with the product. Rest it, in the incubator for at least 16 hours. Now, it’s time to see if it worked. I rinse carefully. As this skin behaves exactly like human skin we can check that there is no change in the cells. Finally, I plunge the reconstructed skin into a liquid to reveal the result. If it turns purple, we know the cells have reacted well. There is no irritation of the skin. We use different methods to test our products including reconstructed skin, the most accurate way to test. At L’Oréal, we do not test on animals.
