Koji-San products with natural kojic acid: against pigment spots, for a light, even, radiant complexion!

Kojic acid is a 100% natural substance. Discovered in Japan, it is a byproduct of koji, or malted rice, and is used in the production of rice wine. This means that kojic acid is completely natural and not created by one person or a group of scientists and dermatologists in a laboratory. In cosmetics, kojic acid is known for its smoothing properties. Kojic acid soap contains other natural ingredients that make kojic acid more effective at lightening dark spots or improving your overall skin tone.

It's also good to know that Kojie San is the only manufacturer that uses rice wine. All other brands use dried mushrooms that contain kojic acid.
