Research & Innovation - Internship 6 months – Augmented Beauty - 2021 - M/W

For L’Oréal, beauty is above all a scientific adventure. This principle is reflected in the key role played by our Research & Innovation division, which deploys its teams all around the world to dream up and create the products of tomorrow.

But wait, have you heard about our history?

In 1909, Eugène Schueller, a young chemist, formulated the first hair dyes using a blend of harmless chemical compounds. With his entrepreneurial spirit, he sold it to Parisian hairdressers and founded the Société Française des Teintures Inoffensives pour Cheveux.

You never heard of that company? Don’t worry, we don’t blame you, because you know it under its current name: L’Oréal.

More than a century later, Eugene Schueller’s belief that research and innovation form the cornerstone of growth and success has spread to reach more than 3800 R&I employees, and enabled the discovery of over 130 molecules and the development of thousands of formulas and products.

Join us to become a L’Oréal Internpreneur!
