In order to respond to the various skin types of men and women around the world, the Active Cosmetics division's laboratories at Chevilly Larue, in Paris area, create formulas for products that are suited to customers worldwide.

Vichy and La Roche-Posay's formula charters are particularly strict to satisfy consumer safety requirements as these skincare products are created for sensitive or hypoallergenic skin. Formulas are minimalist in order to reduce the risk of allergies. The selection of ingredients is particularly rigorous and their traceability is of the highest importance.

The fragile properties of thermal spring water make formula design particularly delicate. Compared to other L'Oréal brands, only a limited selection of ingredients can be combined with spring water. The spring waters also make finding the right dosage of other active ingredients all the more complex when seeking optimal efficiency and a pleasant texture.

All formulas are tested for quality and tolerance on a panel of subjects chosen according to stringently defined skin conditions. These clinical tests are particularly in-depth when applied to highly sensitive, hypoallergenic or atopic skins or when dermatological treatments are in question, as for La Roche Posay products.

Chevilly Larue laboratories elaborate small quantities of formula that are then developed at an industrial level in the plants at Vichy and at La Roche-Posay.
