It is the combination of two words BIO - ONSEN, the Onsen are natural Japanese hot springs, open-air pools surrounded by nature that offer a unique ritual of beauty and well-being, by Bio we mean the bio oligominerals naturally present in the natural Onsen springs, rich in beneficial active ingredients in the development and formation of epidermal tissue and its protective barriers. The entire Bionsen line is the result of the joint development of our laboratories together with the Siena Dermatology Clinic and the Center for Thermal Studies in Tokyo
