Technology research and development

In 1996, a live yeast skin care product was developed and started to be sold in Taiwan, China. Because it had to keep the temperature below 15°C, it could not be marketed.

In 2013, TST extracted yeast from fresh milk, combined with super-micron penetration technology, successfully developed live yeast skin care products, and achieved marketization.

In 2014, the third-generation TST live yeast product was born.

In May 2015, TST applied for a live yeast technology patent from relevant national departments and was accepted. 

As of April 2019, TST has also cooperated with more than 20 external research centers on research and development, innovating more than 200 formulas each year to serve the diverse needs of consumers. In addition, TST Qingpu R&D headquarters has completed in 2019.
