WHEN SCIENCE MEETS DATA, BEAUTIFUL THINGS HAPPEN

Originally founded by a chemist, scientific endeavor has always driven L’Oréal’s thinking and expertise. Our 4 000 scientists in 21 research centers around the world work hand-in-hand to deliver state-of-the-art formulas based on proven results. More than a hundred experts are specialized in product safety and efficacy alone, and all our formulas are screened to ensure that the diverse ingredients work in harmony and are used in safe quantities.

Creating tools to measure the performance of any scientific advance is crucial. That is why L’Oréal has developed Skin Atlases of all ethnicities, to objectively compare the effects of products and treatments. Each product is tested on a wide diversity of skin and hair colors and types and among different age groups.

Thanks to such data and knowledge, we can promise tried and tested results and truly superior efficacy, and it is thanks to this transparent, human vision of science that we have built the trust of consumers over the years and continue to do so.
