Japan Quality

Japanese consumers have a great interest in the safety and the efficacy of cosmetic products. Certification according to Japanese safety standards or efficacy claim guidelines will help to build trust of people around the world as well as trust from the Japanese market. Kirei Testing Labo, as a leading Japanese "Contract Research Organization" (CRO) in Tokyo Japan, examines the safety and the efficacy of cosmetics and their ingredients. We, in accordance with OECD princeples of Good Laboratory Practice "GLP", provide wide varieties of non-clinical and clinical tests with high standards qualified by Japanese regulations and consumers.
