A story made in France

Laboratoires Expanscience are a pharmaceutical and dermo-cosmetic laboratory created in 1950. Today, we are proud to work in a committed family business, because we know where we come from and where we are going. This allows us to make strong and often pioneering strategic choices.

An example ? The decision taken in 2004 by our president Jean-Paul Berthomé to voluntarily commit Expanscience to a Corporate Social Responsibility (CSR) approach, with the signing of the United Nations' Global Pact.
