BACILLUS/ZIZANIA LATIFOLIA LEAF EXTRACT FERMENT FILTRATE.

Valuable / ANTIOXIDANT, SKIN CONDITIONING

A high-precision botanical active produced through the Bacillus-mediated fermentation of Manchurian wild rice leaves. This process concentrates the flavone tricin, resulting in a bioavailable extract that significantly reinforces the skin's defense against photo-oxidative stress and enzymatic collagen degradation.

Science

The filtrate functions through a dual-action pathway: it acts as a potent scavenger of Reactive Oxygen Species (ROS) and a direct inhibitor of Matrix Metalloproteinases (MMP-1, MMP-3). By suppressing NF-κB inflammatory signaling and preventing UV-induced lysosomal exocytosis, it halts the breakdown of the dermal matrix and preserves collagen-1 levels.

Key findings

  1. 01 In vitro analysis confirms that 100 μg/mL (0.01%) significantly inhibits UVA-induced ROS and preserves collagen-1 by reducing MMP-1 expression.
  2. 02 A 12-week human clinical trial demonstrated significant improvements in dermal hydration and a reduction in wrinkle depth following standardized extract administration.
  3. 03 In vivo modeling indicates that topical applications between 1.0% and 2.0% suppress photoaging markers, including keratinization and coarse wrinkle formation.

While cellular benefits are seen at very low concentrations (0.01%), visible structural improvements in wrinkle depth and barrier repair typically require inclusion rates of 1.0% or higher. Many products use trace amounts to claim 'fermented' benefits without reaching therapeutic tricin levels.
