Bacillus/monascus/prunus Tomentosa Fruit/soybean Ferment Filtrate

A sophisticated probiotic-mimetic bi-ferment engineered through the symbiotic action of bacteria and red yeast on Nanking Cherry and Soybean. This nutrient-dense filtrate serves as a multi-functional bioactive complex that fortifies the skin's microbiome while delivering potent antioxidant protection.

Antioxidant Skin Conditioning Microbiome Support Emollient Barrier Repair

Science

Mechanism of Action

This ingredient operates through a dual-fermentation pathway: Bacillus bacteria cleave soybean proteins into bio-available peptides for barrier restoration, while Monascus yeast transforms Nanking Cherry polyphenols into concentrated anthocyanins and vitamins A and C. Together, they neutralize oxidative stress and stimulate cellular regeneration by providing the skin with essential amino acids and isoflavones.
