Aspergillus/Rice Ferment Extract

What is Aspergillus/Rice Ferment Extract?

Aspergillus/rice ferment extract is the koji-transformed skin illuminator—a specialized ingredient created when Aspergillus oryzae (the same fungus used to make miso and soy sauce) ferments rice, creating a wealth of skin-brightening enzymes and organic acids. This traditional fermentation process generates kojic acid, a natural tyrosinase inhibitor that reduces melanin production, along with multiple beneficial moisturizing factors. Think of it as traditional culinary techniques repurposed for beauty—the same processes that develop complex flavors in food developing complex benefits for skin. It's the skincare equivalent of umami for your face—an enhancement of overall quality that's subtle yet transformative. For those seeking gentle but effective brightening with additional moisturizing benefits, this ferment offers traditional efficacy backed by modern research, delivering more even tone and improved clarity with continued use.
