Those who are beauty-conscious currently have their eyes on the power of yeast, and “cobon” is the brand at the center of the industry for many years. Yeast is the microorganism that produces enzymes. This plant extract fermented drink is packed with natural yeast traditionally used in Japan to make fermented foods such as miso, soy sauce, and sake. The natural yeast drink by cobon is a long-selling brand of handmade products made in Izu since 1950. Basing on this technology, the company very carefully cultivated the seed yeast that has been passed down for over 60 years to create the cobon N series.
