our commitments

We have a responsibility towards our children

As a brand of Laboratoires Expanscience, a mission-driven company since 2021, we recognize our responsibility and the potentially negative impact of our products throughout their entire life cycle. In line with our commitment to the well-being of the children and families we support every day, we therefore implement numerous actions to assess this impact and seek to reduce it as much as possible.

Sourcing

Capture_d_ecran_le_2025-09-01_a_10 - Mustela Multi-market - 1

Ingredient sourcing selection

Some of our active ingredients come from traceable plant-based supply chains. As part of this commitment, we are a member of UEBT (Union for Ethical BioTrade) and support its “Sourcing with Respect” standard. We are engaged in a continuous improvement approach to advance our ethical sourcing practices.

Naturally Derived and Organic Ingredients

Since our founding, we have prioritized the finest ingredients from the plant world while ensuring product safety through a stringent formulation charter. Most of our ingredients are of natural origin, enabling us to achieve an average of 96% naturally derived ingredients across our formulas (according to ISO 16128). We exclude genetically modified organisms (GMOs) as well as animal-derived ingredients, with the exception of bee products. A selection of our products is certified organic.

Upcycling

We are experts in plant extraction, and our processes are designed to make the most of every part of the plants we use.

For example, we transform avocados that would otherwise be discarded into cosmetic active ingredients found in our products. From the skin to the pit, the entire fruit is valued and transformed into oil and powder, which are used to produce Avocado Perseose, found in our products intended for normal skin.

As part of the same upcycling approach, the passion fruit seeds we use come from the food industry: previously unused, they now find a second life at the heart of the formulas in our maternity range (excluding the Nursing Comfort Balm).

Composition and production

Plant extraction processes

We use molecular distillation - a non - chemical process that separates and concentrates the premium components of the oil - and biotechnologies such as enzymatic engineering, which replaces chemical substances.

Reducing our consumption

Between 2010 and 2020, at our Épernon production site (where 85% of our products are manufactured), we have reduced electricity consumption by 19.4%, gas consumption by 24.6% (1) and water consumption by 13.2% (2)
(1) Gas and electricity consumption at the Épernon site (Reference years: 2010 and 2020),
expressed in MWh and converted into Wh per unit produced (cosmetics, pharmaceuticals
actives, active ingredients). All energy uses are taken into account, including heating, lighting, industrial processes and any other uses.
(2) Total volume of water consumed over one year (Reference years: 2010 and 2020) at the Épernon site, expressed per unit produced (all types of products: cosmetics, pharmaceuticals actives, active ingredients).

Packaging and distribution

Our packaging initiatives

Since the early 2010s, we have been committed to reducing the impact of our packaging.
For instance, all Mustela boxes are made from the widely recognized certification for good forest management.

Our bulk offering

Mustela aims to gradually support consumers in adopting more reuse-oriented consumption habits, without compromising on safety or the user experience.

We know that 63% of French consumers would like to be able to purchase their everyday products in bulk*. That is why we joined the Pharmarecharge pilot project which aims to transform consumption habits by offering a practical alternative to single-use plastic bottles in pharmacies.

Optimization of routes and reuse of cardboard

GEODIS, our storage warehouse, is located less than 800 meters from our manufacturing plant (which is certified to ISO 14001, the international environmental management standard).

Did you know? The cardboard boxes used at our Mustela production facility are given a second life. We reuse them to ship some of your orders instead of using new large shipping boxes. In 2025, this allowed us to save 2.8 tonnes of cardboard intended for destruction.
