The research and development of CalmYang lasted more than four years. From more than 200 kinds of plants, seven kinds of natural plant compound plant desensitizers with natural safety and therapeutic effect were obtained by layer-by-layer screening of inflammatory promoter activity analysis.
Since 2004, the Institute of Life Sciences has conducted a one-year clinical trial on CalmYang in Seoul National University School of Medicine. The test results show that CalmYang has a good effect of repairing skin barrier, and subsequent related in vitro tests also show that CalmYang has an excellent effect of inhibiting inflammatory factors.
