A story made in France
70 years of a human adventure.
70 years of a human adventure.
You don't give your all without a good reason... At Expanscience, we help individuals shape their well-being, from the youngest to the oldest.
It's what has inspired us to move forward, carry out research, and innovate for over 70 years!
We’ll state it up front: the Expanscience teams are proud to work for a French family-owned group. Why? Because this explains our roots and our ability to have a long-term vision.
We know where we come from and where we’re going. This enables us to make strong strategic choices that are often pioneering, such as the decision made in 2004 by our President, Jean-Paul Berthomé, to voluntarily commit Expanscience to a Corporate Social Responsibility policy.
What we are today we owe to an encounter between two men in 1950. On the one hand, Paul Berthomé (father of the current president of Expanscience), a businessman and industrialist. On the other, Claude Guillon, a pharmacist.
Together, they decided to undertake the design, production and marketing of a lotion for babies that cleansed tender skin while moisturizing it. At the time, this was a revolution, as was the wish to develop and manufacture using the same quality criteria as those drawn up for pharmaceutical products.
It was the birth of our Mustela brand and the start of our company adventure!
The adventure starts with the creation of Laboratoires Expanscience and our Mustela brand.
We use our know-how in the area of fatty substances and molecular distillation to create a cosmetic active ingredients business.
The Mustela Foundation is created to support research projects focusing on child development and parenting.
With Piascledine 300, we enter the Rheumatology area and provide support for patients suffering from osteoarthritis.
Building on our values and the commitment of our teams, we join the United Nations Global Compact.
Our CSR policy is recognized as “Exemplary” with the CSR Committed label
Our company takes another step forward by becoming the world’s first pharmaceutical and dermo-cosmetics laboratory to receive B Corp certification.
We launch our impACT strategy to become a regenerative company with a positive impact by 2030/2040.
We become a mission-driven company: a major step forward in transitioning to a model with a positive impact.
We plan to reach a goal of contributing to planetary carbon neutrality with our Mustela brand and our cosmetic active ingredients business.
In 1957, the two founders of Expanscience decided to implant their production site at Epernon, a small town in the Eure-et-Loir department.
Since then, the town and our laboratory have written their history together. This site has never stopped being at the core of our transformations and development.

All the French know-how of Expanscience radiates throughout the word from Epernon. Our historical site is home to both our Innovation, Research and Development (IR&D) and production teams, representing approximately 300 employees.

Our local implantation at Epernon is an integral part of our identity and commitment. Our site is fully part of local and departmental life and is one of the local economic lungs.
There is greenwashing... and then there are committed companies like Expanscience. As proof of this, our Epernon site is the first place where we apply our commitments to societal and environmental responsibility. It has thus been recognized with a number of certifications for quality, management and environmental protection.
