Successful recertification

Our company successfully passed the recertification audit ISO 9001: 2015 and at the same time switched to a new scheme GMP+2020. The certificates were issued by Lloyd’s Register Quality Assurance for another 3 years.


After a two-year break, you can meet our colleagues at trade fairs, currently at In cosmetics in Paris.
