What Is Lactobacillus/Wasabia Japonica Root Ferment Extract?
Lactobacillus/Wasabia Japonica Root Ferment Extract is made by fermenting the spicy green root of Wasabia japonica with the probiotic microbe Lactobacillus. The process breaks the root’s tough cell walls, releasing natural compounds like isothiocyanates, phytonutrients and gentle acids. When the fermentation is finished the mixture is filtered, leaving a water-soluble extract that blends smoothly into creams and serums.
Wasabi has been prized in Japanese cooking for centuries, and its strong antioxidant activity caught the eye of skin care formulators in the early 2000s. Fermentation was chosen because it lowers odor, tones down the sting of raw wasabi and boosts the bioavailability of its protective molecules.
Today this fermented extract shows up in lightweight moisturizers, anti-aging lotions, sheet masks, after-sun gels and specialty treatments aimed at giving the skin an extra layer of defense against daily stressors.
