Kojie San Skin Lightening Soap 135g

Kojie San products with natural kojic acid: for pigment spots, for a light, even, and radiant complexion!

Kojic acid is a 100% natural substance. Discovered in Japan, it's 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 developed by one person or a group of scientists and dermatologists in a laboratory. In cosmetics, kojic acid is known for its skin-smoothing properties.
Koji San soap contains other natural ingredients that make kojic acid more effective at lightening dark spots and improving your overall complexion.

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

How does kojic acid work?
Now that you know what kojic acid is, you're probably wondering how it works. Kojic acid works in a unique and effective way, especially considering it's completely natural.

Simply put, Kojie San helps reduce melanin production in the skin. Melanin is the substance that gives your skin its pigment.
