NK‑061 – Bifida Ferment Filtrate (Concentrate) | Multi‑Solution Active for Next‑Gen Cosmetics
Product Overview:
NK‑061 is a clear, concentrated filtrate obtained from the controlled cultivation, inactivation, and decomposition of Bifidobacterium longum (also known as Bifida yeast). It is rich in organic acids, amino acids, trace minerals, and bioactive polysaccharide complexes. Unlike cell lysates, this filtrate focuses on the metabolites – the true functional drivers for skin health.
Key Metabolites & Mechanisms:
-
Lactic acid & acetic acid → optimise skin pH, enhance mineral absorption (Fe, P, Ca), support vitamin D utilisation.
-
Bioactive polysaccharides → superior hydration & antioxidant protection with a lightweight skin feel.
-
Small‑molecule organic acids, amino acids & vitamins → exfoliate, nourish, and fight visible ageing.
