About the Faith Group

Bio-Science Research Center

The Bio-Science Research Center lies at the heart of the Faith Group’s active oxygen research initiative.
The Center was founded by Doshisha University professor emeritus Hajime Nishioka, who conducted research into active oxygen, which is considered a cause of adult-onset diseases and aging, for many years.
The Faith Group’s cosmetics are required to pass the Kat Sod Assay method.


Faith is grateful to Doshisha University professor emeritus Hajime Nishioka, who developed this method.
