Founded by a researcher, L'Oréal has founded its development on a platform of scientific knowledge of hair and skin, accumulating in over a century of existence a unique capital in the cosmetics industry. Scientific progress is still today the driver of its success. Originally focused on chemistry, L'Oréal's Research and Innovation opened up with the same degree of ambition and exacting standards to life sciences and the study of materials, and to biotechnologies, to ensure a continuous flow of innovations in each category of products and to respond in this way to the needs of men and women from around the world. The Research and Innovation teams, which have grown by 8 times in 20 years, constantly aim to be in the forefront of scientific advances, in particular by collaborating with the world's leading experts in each field. Each year, the results of their work are the object of several hundred patent filings and result in thousands of formulas.
