19 years ago, Chang Ting and her husband Lin Rui Yang discovered a type of milk-derived yeast that can retain skin youthfulness on a trip to France. They decided to bring this active ingredient back to Taiwan for research and development so that this active ingredient can be used in skincare products. After 19 years of research and development, they have successfully developed the world’s one and only skincare product range with active yeast as the main ingredient. This active yeast series is named after the brand spokesperson Chang Ting- “Tin’ Secret”.
