Yes. The cream, like serums, has passed two stages of certification. First, the technologists sent the samples to an independent laboratory, where they examine the microbiological, toxicological, physicochemical, and clinical and laboratory parameters of cosmetic products. The protocols obtained during these tests were submitted by the laboratory to the certification authorities according to ISO 22716:2007, the international standard for the Good Manufacturing Practices (GMP) for cosmetics. ISO 22716 provides guidance to documenting and regulating the production, control, storage, and shipment of cosmetic products. These documents were accurately checked and based on the check a declaration of conformity was issued.
