In the year 2000, with Gerland technology, L’Oréal built a production for epidermis reconstruction. The aim was to industrialize the technology that had been mastered in laboratories twenty years prior and which was used for research in biology, alternative methods and skin-tolerance testing. At the time, the 200 m2 building housed fifteen people and produced 12,000 units of reconstructed epidermis per year.
Ten years later, L’Oréal has doubled the size of the building and multiplied its personnel by four, annually producing more than 160,000 units of biologically reconstructed tissue (skin and cornea) while developing safety and effectiveness testing.
The biotechnological station has changed. It is now a veritable testing center for predicting safety and effectiveness – a unique platform in the global cosmetic industry, illustrating L’Oréal’s unwavering commitment to an unavoidable ethical shift: the renouncing of animal testing. Why have things moved so fast? Because technology is evolving, because teams have the desire to meet this challenge and, above all, because a profound revolution in testing for toxicity and safety is underway. Pure and simple testing has given way to predictive testing. In other words, it is now about predicting a harmful or beneficial effect based on the molecular structure of a substance.
These reconstructed tissues are amazing tools, for they allow us to test products applied under real conditions, on the surface of the epidermis – be it a gel, cream, liquid, paste or powder.
New data is enhancing 100 years of research, which will allow us to eventually begin risk-free human clinical trials via a chemical structure, eliminating animal testing all together. A revolution symbolic of a changing world. In this way, L’Oréal’s forward-thinking vision, animal-free ambition and consumer trust are being strengthened.
