BACILLUS/SOYBEAN FERMENT.

Essential / SKIN CONDITIONING

A potent biotechnological active derived from the microbial fermentation of soy proteins by Bacillus bacteria. This process transforms standard soybean nutrients into highly bioavailable peptides, amino acids, and polyglutamic acid to deliver superior hydration and structural skin support.

Humectant Skin-conditioning agent Antioxidant Skin brightening Soothing

Science

The fermentation process utilizes Bacillus-driven proteolysis to convert soy glycosides into bioactive aglycones like genistein and daidzein, which possess enhanced antioxidant and skin-brightening properties. It synthesizes Gamma-Polyglutamic Acid (gamma-PGA) to lock in moisture more effectively than hyaluronic acid, while also increasing adiponectin release to improve cellular ATP production and metabolic efficiency.

Key findings

  1. 01 In vivo testing at 5% concentration demonstrated a 1.6 cm reduction in abdominal contour and a 66.5% decrease in subcutaneous fat thickness over 56 days.
  2. 02 A 1% concentration significantly elevated antioxidant potential, increasing total isoflavone aglycones by 32.71% and radical scavenging by 121.18%.
  3. 03 Laboratory filtrates showed dose-dependent tyrosinase inhibition up to 12.89% for skin-tone evening.
