1950
A family-owned business, Expanscience is the result of two sets of expertise coming together: that of industrialist Paul Berthomé, and that of pharmacist Claude Guillon. The two men join forces in 1950, driven by a shared ambition – to create dermatological hygiene products, designed using pharmaceutical methods to guarantee their quality and ensure the safety of consumers.
The launch of the first Mustela cleansing lotion is a revolution at the time and marks the beginning of the Dermo-Cosmetics business.

Very early on, the decision is made to use pharmacies as a means of distributing and selling the products. In pharmacies, mothers can be sure that the products they purchase have taken a secure route to get to them, but they also know they can get expert advice from pharmacists.
