ASPERGILLUS/RICE/SOYMILK FERMENT FILTRATE.

Essential / SKIN CONDITIONING

A nutrient-dense bio-active liquid derived from the precision fermentation of rice and soymilk using Aspergillus oryzae. This process breaks down complex proteins and polysaccharides into highly bioavailable peptides, amino acids, and isoflavones that fundamentally enhance the skin's moisture-retention architecture.

Humectant Barrier Repair Brightening Anti-aging Antioxidant

Science

It functions as a multi-pathway biological modulator: it upregulates the Aquaporin-3 (AQP3) and Filaggrin (FLG) proteins to improve cellular water transport and barrier integrity. Simultaneously, it stimulates the synthesis of Hyaluronic Acid and Ceramides while inhibiting tyrosinase and elastase enzymes to brighten tone and preserve structural elasticity.

Key findings

  1. 01 Observed a 26.93% increase in stratum corneum hydration levels at a 1.25% concentration via AQP3 and FLG upregulation.
  2. 02 Demonstrated a 198% boost in collagen synthesis when 0.25% ferment was combined with Sialic Acid, stabilizing collagen mRNA.
  3. 03 Achieved a 71% increase in AQP3 protein content and 51% increase in Filaggrin expression at a 3.0% concentration.

Because this ingredient is effective at very low concentrations (as low as 0.25%), brands often include it at 'label-only' percentages below 0.1% to claim fermentation benefits without reaching the threshold for biological efficacy.

Stability

Highly stable in aqueous solutions; however, it must be incorporated during the cooling phase below 45°C to protect its heat-sensitive bioactive enzymes.

Synergies

  • Sialic Acid (for collagen synthesis)
  • Niacinamide
  • Hyaluronic Acid
  • Peptides

Conflicts

  • Extreme pH levels below 3.5 or above 8.0
  • Strong oxidizing agents
  • High thermal processing (>50°C)
