Kao Corporation has established a technique to stably store and transport Skin Surface Lipids-RNA (SSL-RNA) at ordinary temperature in a further development of “Skin Surface Lipids-RNA Monitoring”^*1 to grasp various conditions of the body and skin by analyzing the SSL-RNA collected from sebum.

This will expand the situations in which Skin Surface Lipids-RNA Monitoring can be utilized, as SSL-RNA can be collected anywhere, including one’s home.

Utilizing this technique, in cooperation with Healthcare Systems Co., Ltd., Kao has been developing a mail-in testing service that will enable consumers to assess their health at home, and conducting tests for implementing and providing the service within 2022.
