L'Oréal's research facilities in France, the USA, and Japan bring together more than 3,000 scientists and research staff. Their discoveries are published in leading scientific journals. L’Oréal’s innovations are patented, creating some 586 patents in 2004 alone.
Our methodologies for evaluating the safety and efficacy of ingredients and finished products, product evaluation and claim substantiation are recognised by the international scientific community.
L’Oreal Paris products are the result of the following research, development and evaluation process:
1. The benefits offered by our products are supported by the scientific and customer evidence gathered at 13 research centres, 13 evaluation centres and through collaborations with leading independent research institutes around the world.
2. L’Oréal Paris products are validated by independent cosmeto-clinical studies under dermatological control to assess their efficacy and safety. The sample size of these cosmeto-clinical studies is in line with the industry’s standards.
3. In addition, L’Oréal Paris conducts consumer studies to assess the products’ efficacy and satisfaction rate before they are launched. These tests are conducted by independent research companies and performed on a statistically significant number of women and men.
4. Moreover, customer satisfaction surveys are carried out after the products are launched. These involve interviewing a statistically significant number of people who have bought and used the products for several weeks to assess their level of satisfaction and to help us to continually improve our products.
