DESCRIPTION: Kefir Ferment Filtrate is a bio‑fermented active produced by fermenting soybean extract with Lactobacillus cultures. The fermentation process generates postbiotics, including peptides, amino acids, organic acids, polysaccharides, and beneficial metabolites that help support the skin’s microbiome, barrier function, and overall resilience. It is known for its probiotic‑rich, skin‑balancing properties. In skincare, it acts as a microbiome‑friendly, soothing, and barrier‑restoring active suitable for all skin types, especially sensitive or compromised skin.
MECHANISM OF ACTIVITY
Kefir Ferment Filtrate is supported by research showing that it helps strengthen the skin barrier, increase ceramide production, and reduce transepidermal water loss. Postbiotics produced during fermentation have been shown to balance the skin microbiome, reduce harmful bacteria, and calm inflammation by lowering cytokines such as IL‑6 and TNF‑α. Studies on fermented soy also demonstrate enhanced antioxidant activity, improved hydration, and better elasticity compared to non‑fermented soy. Together, these findings support Kefir Ferment Filtrate’s ability to soothe irritation, reinforce the barrier, and improve overall skin resilience and smoothness.
