Question: 1 / 400

What is a known source of kojic acid?

Derived from bacteria on a Japanese mushroom

Kojic acid is a well-known compound primarily derived from a specific type of fungus, particularly the Japanese mushroom called Aspergillus oryzae. This mushroom is cultured during the fermentation process of sake, which contributes to the production of kojic acid. This natural source is significant because kojic acid is often used in skin care products for its ability to brighten the skin and inhibit melanin production, making it a popular ingredient for treating hyperpigmentation and promoting an even skin tone.

While synthesized forms of kojic acid exist, and it can be associated with other sources, the most recognized and traditional source remains the fermentation of this specific mushroom. The other options may relate to substances that can provide skin care benefits or serve as acids, but they do not accurately represent the original and primary source of kojic acid.
