ASPERGILLUS/DEFATTED SOYBEAN SEED FERMENT EXTRACT FILTRATE.

Valuable / HUMECTANT, SKIN CONDITIONING

An advanced bio-transformed active obtained by fermenting defatted soy seeds with Aspergillus fungi to unlock highly bio-available micronutrients. This process yields a nutrient-dense filtrate rich in small-molecule peptides and amino acids that significantly improves skin moisture retention and structural integrity.

Humectant Skin Conditioning Antioxidant Barrier Repair Brightening

Science

This ingredient functions through enzymatic bioconversion, reducing large soy proteins into low-molecular-weight peptides for deeper skin penetration. It actively upregulates Hyaluronic Acid (HA) levels by inhibiting the hyaluronidase enzyme (HYAL2) while stimulating HA synthase (HAS) and Glycosaminoglycan (GAG) production; additionally, it provides a brightening effect by inhibiting tyrosinase activity to modulate melanin synthesis.

Key findings

  1. 01 Human clinical trials utilizing Corneometer CM825 measurements confirmed a significant increase in skin hydration on both the face and forearms following application.
  2. 02 In vitro analysis at 50 µg/ml demonstrated a downregulation of adipogenic genes, suggesting benefits for skin texture refinement.
  3. 03 Standard commercial benchmarking identifies 1.0% to 10.0% as the effective range for barrier repair and hydration in high-potency essences.
