In 2007, Clarins Laboratories were the first on the selective distribution market to obtain GLP (Good Laboratory Practice) approval.
 
To ensure excellence in all its products, the Clarins group masters its production chain from A to Z. It has its own research laboratories in France, based in Pontoise.  They verify the effectiveness and stability of products through safety and tolerance testing, completed both in vitro and in vivo.
 
Most Clarins products are made in France at the Pontoise site. As for the fragrances, they come from a second laboratory based in Strasbourg. They are then distributed worldwide.
Managed by the quality department, manufacturing of the products is carried out according to strict health rules and always in compliance with good manufacturing practices. Environmental laboratory management is provided by a specific department - the health and environmental safety department.
