Our expertise

We produce very high-quality plant extracts, oils, powders and purified butters, which undergo rigorous biological and clinical testing, patent filings and scientific publications to ensure proven tolerance and efficacy.

With 40 years of experience in the field of plant raw materials, Laboratoires Expanscience has become a key supplier for cosmetic brands in France and internationally.

In its laboratories, Mustela® favours plant extraction through eco-socially designed processes: molecular distillation, a "green" separation and concentration method for the noble elements of oils; biotechnologies such as enzymatic engineering, an alternative to certain chemicals; and plant extraction using "green" solvents.

All of the plant supply chains that allow us to develop and obtain our actives — such as avocado and schisandra — follow the principles of our CSR policy.

We prioritise:

Organic farming over conventional agriculture; the circular economy, which aims to limit resource waste and environmental impact; upcycling — recovering materials or ingredients that are no longer used in the creation of products, i.e. the use of food industry co-products created during the manufacture of a food item from the same raw material.
