ASPERGILLUS/RICE BRAN FERMENT EXTRACT.

Valuable / HUMECTANT, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A bio-transformed botanical extract produced by fermenting nutrient-rich rice bran with the fungus Aspergillus oryzae. This precision process yields a high-bioavailability cocktail of peptides and organic acids that target both structural aging and epidermal hydration.

Summary

humectant skin-conditioning anti-aging brightening

Science

Mechanism of Action

Through enzymatic decomposition, Aspergillus oryzae breaks down complex rice proteins into smaller, readily absorbed peptides and increases the density of phenolic compounds like ferulic and gallic acids. These molecules inhibit tyrosinase to brighten skin, suppress elastase to protect fiber integrity, and actively upregulate the genetic expression of Type I and Type III collagen.

Key findings

  1. 01 A 30-day clinical evaluation of a 20% concentration demonstrated a 44.31% increase in dermal moisture and a 9.29% improvement in skin luminosity.
  2. 02 In vitro analysis at ultra-low concentrations (0.0001%-0.001%) significantly stimulated fibroblast proliferation and the synthesis of collagen and elastin.
  3. 03 In vivo modeling showed a 10% increase in collagen deposition and measurable improvements in the skin's elastic coefficient.

While this ingredient shows cellular activity at extremely low levels, the most significant moisture and brightening benefits recorded in human clinical trials require concentrations closer to 20%. Products containing less than 1% are unlikely to deliver the dramatic structural improvements promised by fermented rice technology.

Stability

The extract is highly stable in aqueous formulas but should be processed under 40°C to preserve the integrity of heat-sensitive phenolic antioxidants like ferulic acid.
