Research and analyses conducted by the dermatological clinic of the University of Siena, in collaboration with the Spa Study Centre in Tokyo, have led to the innovative Bionsen formula based on Japanese spring oligominerals; protective and regenerating bioelements which are abundant in Japanese hot springs. 

The Brand in short

Bionsen springs from the synergy and cultural blend of the Western and Eastern worlds. Trace minerals are essential for normal epidermal trophism and it is on these bases that the Coswell research laboratories have further exploited their application by using them in their cosmetic products in appropriate concentrations.


Bionsen is a complete line of products for personal hygiene and wellness: shower gel and bath foam, shampoo, liquid detergents, deodorants and a line of products specifically designed for personal hygiene. See the full range of Bionsen products.
