Lactobacillus/Citrus Junos Fruit Ferment Filtrate

What is Lactobacillus/Citrus Junos Fruit Ferment Filtrate?

Lactobacillus/Citrus Junos Fruit Ferment Filtrate originates from fermenting the fruit of Citrus junos, or yuzu—a citrus species from East Asia—using Lactobacillus, a lactic acid bacterium. This process produces a cell-free filtrate rich in fermentation byproducts like organic acids, peptides, and polysaccharides from the fruit. In cosmetics, it serves as a skin conditioning agent in categories such as moisturizers, serums, and essences. It works by promoting hydration through humectant-like properties and supporting the skin's moisture barrier via bioactive metabolites. The fermentation breaks down yuzu's components, potentially increasing the stability and skin affinity of natural compounds like flavonoids and vitamin derivatives, making it suitable for gentle, daily topical applications without the volatility of fresh fruit extracts.
