ASPERGILLUS/RICE FERMENT.

Valuable CAS - / HUMECTANT

A nutrient-dense bioactive created through the precision fermentation of rice by the Aspergillus oryzae fungus. This multifaceted extract serves as a cellular messenger, significantly enhancing the skin's natural ability to retain moisture while promoting a more luminous, even-toned complexion.

humectant antioxidant skin brightening barrier repair

Science

This ingredient operates via a quadruple-action pathway: it upregulates key hydration markers like Aquaporin 3 and Hyaluronan Synthase 1, stimulates dermal fibroblasts to boost Collagen and Elastin synthesis, inhibits tyrosinase to suppress melanin production, and reinforces the epidermal barrier by increasing junctional proteins such as Filaggrin and Involucrin.

Key findings

  1. 01 In vitro testing at 1.25% demonstrated a 26.93% increase in epidermal water content via mRNA upregulation of HAS1 and AQP3.
  2. 02 Keratinocyte models using a 3% concentration showed a 71% improvement in Aquaporin 3 protein expression and a 51% increase in Filaggrin levels.
  3. 03 Solid-state fermentation processes have been shown to increase tyrosinase inhibition by up to 11.2-fold compared to non-fermented rice counterparts.

Due to its high marketing appeal as a 'fermented' ingredient, it is often included at concentrations below 0.5% for storytelling. However, clinical data suggests a minimum threshold of 1.0% is required to trigger significant biological responses in hydration and barrier repair.

Stability

Demonstrates exceptional thermal stability from -25°C to +50°C. It is most stable in slightly acidic environments (pH 5.0–6.0), reflecting its original fermentation conditions.

Synergies

  • Niacinamide
  • Hyaluronic Acid
  • Vitamin C

Conflicts

  • Strong oxidizing agents
  • Highly alkaline environments (pH > 8.0) which may denature bioactive peptides
