BACILLUS/MONASCUS/SESAME SEED/SOYBEAN FERMENT FILTRATE.

Valuable / ANTIMICROBIAL, ANTIOXIDANT, HAIR CONDITIONING, LIGHT STABILIZER, SKIN CONDITIONING

This advanced bio-active complex leverages dual-strain fermentation to transform plant-based lignans and isoflavones into highly bioavailable aglycones. It serves as a multifunctional powerhouse, offering superior melanin inhibition and antioxidant protection while acting as a natural photostabilizer for cosmetic formulations.

Summary

Antioxidant Brightening Agent Skin Conditioning Photostabilizer Antimicrobial

Science

Mechanism of Action

The fermentation process utilizes Bacillus and Monascus microorganisms to enzymatically convert inactive glycoside isoflavones from soybean and lignans from sesame into bioactive aglycone forms like daidzein, genistein, and sesaminol. These smaller molecules penetrate the skin barrier more effectively. Additionally, the process generates secondary metabolites, specifically monascin and ankaflavin, which provide robust antioxidant defense and protect the formula from light-induced degradation.

Key findings

  1. 01 A 5% concentration demonstrated more potent inhibition of melanogenesis in B16F10 cells compared to arbutin.
  2. 02 The fermentation process yielded a 33.4-fold increase in isoflavone aglycones and a 3.0-fold increase in CoQ10 levels.
  3. 03 Significant enhancement in tyrosinase and elastase inhibitory activities was observed post-fermentation.
