ASPERGILLUS/SOYBEAN GERM FERMENT.

Valuable / ANTIOXIDANT

A biotechnologically advanced ferment that utilizes Aspergillus fungi to unlock the latent bio-activity of soybean germ. This precision ingredient enhances the skin's structural integrity by converting soy glycosides into potent aglycones for superior collagen and hydration support.

Summary

antioxidant humectant skin-conditioning collagen-booster brightening-agent

Science

Mechanism of Action

Operates through enzymatic bioconversion, transforming inactive daidzin and genistin into bioactive daidzein and genistein. These phytoestrogens stimulate collagen synthesis and inhibit the HYAL2 enzyme to prevent internal hyaluronic acid degradation. Additionally, it suppresses tyrosinase activity to mitigate hyperpigmentation and provides a 205-fold increase in radical scavenging capacity through fermented phenolic metabolites.

Key findings

  1. 01 Demonstrated a 205-fold increase in hydroxyl radical scavenging activity post-fermentation compared to raw soy germ.
  2. 02 Inhibition of the HYAL2 enzyme observed at concentrations between 0.1% and 5.0%, leading to increased fibroblast hyaluronic acid content.
  3. 03 In vitro downregulation of leptin and adipogenin genes at ultra-low concentrations (0.005%) to inhibit fat accumulation.

Due to its high manufacturing cost and the marketing appeal of 'fermented' ingredients, it is frequently included at 'label-only' concentrations. Formulas below 0.1% likely fail to provide the significant antioxidant and hyaluronidase-inhibiting benefits observed in clinical data.
