On Apr. 2, 2026, L’Oréal and the Institut Pasteur announced a landmark research partnership, marking a historic first for both organizations. This collaboration represents the first scientific agreement of its kind between the world-renowned center for biomedical research and one of the global leaders in skin sciences.

This strategic partnership brings together two world-leading French institutions, both driven by a shared belief that skin – the largest organ of the human body – is the silent witness of each individual’s holistic health, well-being, and quality of life. 

This scientific alliance aims to deepen the understanding of skin as an essential organ of human health, while accelerating the discovery of new biological targets and the development of next-generation active ingredients for advanced skin health solutions. By synergizing L’Oréal’s mastery in advanced research for beauty skin science with Institut Pasteur’s world-leading expertise in immunology, microbiome and skin biomarkers research, the teams will explore the role of microbes and immunity on skin health through a cutting-edge biological lens.
