Fermented Vegetable

What is Fermented Vegetable?

Fermented Vegetable is derived from plant materials like cabbage, radish, or other vegetables processed through microbial fermentation, typically involving lactic acid bacteria. This natural biotechnology converts starches and fibers into bioactive components such as organic acids, peptides, vitamins, and enzymes. Commonly featured in natural and organic cosmetics, it appears in moisturizers, shampoos, deodorants, and oral rinses. In formulations, it acts by drawing moisture to the skin and hair (humectant properties), smoothing surfaces (emollient effects), enhancing texture and flexibility (conditioning), neutralizing odor compounds (deodorant action), and aiding freshness in oral products. The fermentation process improves ingredient stability, solubility, and gentle compatibility with skin and scalp microbiomes compared to unfermented plant extracts.
