What is Seiso?

Skincare minimalism.
Our name, pronounced SAY-soh, is inspired by the third of five principles in the Japanese 5S philosophy. The Seiso principle means “clean, tidy, elegant” while the 5S philosophy emphasizes daily improvement, clearing away the unnecessary, and focusing on quality essentials. Less is more.

Ceramide Science

Ceramides keep skin plump, hydrated, protected, and elastic. By the age of 30, we’ve lost approximately 40% of our ceramides, by our 40s, over 60%.
