External Collaboration

Various collaborative activities with individuals outside the company

Advances are made daily in safety research. To be able to conduct evaluations in the most appropriate way, it is essential to acquire the most-up-to-date technologies and information and to share Shiseido's technologies with experts. That is, researchers in safety assurance at Shiseido have been working with outside experts in a wide range of activities. Some of those activities are described below.

・Interactions with outside experts

・Industry activities

・Development of professional human resources

・Basic research on safety

Shiseido’s commitment on alternatives to animal experiments

・Sharing of research findings

Shiseido shares findings obtained from years of research not only on this website, but also through contributing to academic literature and participating in conferences. We strongly hope that due to such efforts, alternative testing methods developed by Shiseido become widely used by a greater number of research institutions, and will continue to improve.

・Further research on alternative methods

Shiseido continues to proceed with its research on alternative testing methods with an aim to further improve measurement accuracy regarding the use of ingredients, and expand the scope of testing while challenging itself to develop alternative in vitro/in silico testing methods for assessing systemic toxicity.

・Efforts on establishing officially acceptable methods and industry standards

<Research commended by specialized academic societies, etc>
