ASPERGILLUS/SOYBEAN GERM FERMENT EXTRACT.

Valuable / ANTIOXIDANT

A biotechnologically refined phyto-extract produced by fermenting the nutrient-dense germ of the soybean with Aspergillus fungi. This process bio-activates the ingredient, breaking down complex molecules into high-potency antioxidants and skin-replenishing peptides for superior absorption.

Antioxidant Skin Conditioning Humectant Firming Agent

Science

The fermentation process utilizes beta-glucosidase enzymes to convert large isoflavone glycosides into smaller, bioavailable aglycones like genistein and daidzein. These smaller molecules penetrate the skin barrier more effectively to neutralize free radicals, while the simultaneous breakdown of soy proteins yields amino acids like GABA and glutamine that reinforce the skin's natural moisturizing factors and structural integrity.

Key findings

  1. 01 In vitro analysis demonstrates that even at low concentrations (0.005%), the extract inhibits adipogenesis, indicating potential for contouring and firming.
  2. 02 Comparative studies show that Aspergillus fermentation increases hydroxyl radical scavenging activity by 205-fold compared to non-fermented soy germ.
