Our answers to your questions
Where do we source the ingredients for our products, and what is their environmental impact?
• Since 2013, as part of the Group’s Sustainability Program, we have shared our commitment and advances in sourcing, responsible production, and collaboration with our partners and suppliers.
• Our Product Environmental and Social Labelling gives a precise assessment of these impacts and the steps that we are taking to mitigate them. Our aim is to empower consumers to make informed and sustainable choices. The labelling system was introduced in 2020 for Garnier haircare products and will be extended to all of our rinse-off products by 2022.
What goes into our products?
• Since 2019, the Inside Our Products website has provided clear and straightforward information on the composition of our products and the ingredients they contain. We created the site in partnership with our science and research teams, and the information provided is based on scientific evidence.
The website features an ingredients glossary, which supplies information about where we source different ingredients and what they are used for, and answers any questions you might have.
Inside Our Products is available in 45 countries and in 8 different languages, ensuring that the information is widely disseminated and easily accessible.
How are our products created and tested?
• Thanks to the expertise we have acquired over the past 25 years in sustainable innovation, green chemistry, and biotechnology, and to the new possibilities offered by recent developments in these fields, we are revolutionizing our research and innovation model with Green Sciences. From the responsible cultivation of raw materials to the extraction of nature's best through processes that combine sustainability and high technology, our goal is to implement a virtuous approach. Green Sciences let us create alternatives to petrochemical ingredients and discover new cosmetic benefits without compromising quality or safety.
• We pay the utmost attention to ensuring that our products exceed your performance, quality, and safety expectations. This standard of excellence is upheld at every stage in the manufacturing process, and we strive to meet it every day.
Product safety and quality are at the heart of our commitments. Together with high performance, they exemplify our commitment to and respect for consumers. This is what allows us to retain the trust of consumers, build the reputation of our brands and maintain L’Oréal’s leadership in this area.

Every L’Oréal employee involved in product development, manufacturing, marketing, and sales must seek to achieve total product quality, from its conception to its distribution, even after it has been put on the market.”

By 2030, under the L’Oréal for the Future commitments
- 95 % of our formula ingredients will be bio-sourced, derived from abundant minerals or circular processes.
- 100 % of our formulas will be respectful of all aquatic ecosystems.
Thanks to the possibilities opened up by science and technology, we are constantly innovating to offer our consumers products that meet their testing-related expectations. We stopped testing products on animals in 1989, and since the 1980s we have used human skin models and reconstructed skin in labs for our in vitro testing. Now, we are using bioengineering and reconstructed skin to reinvent the testing process.
