Science
Mechanism of Action
This ferment extract functions through a synergistic blend of beneficial compounds. Peptides, due to their smaller molecular size, can effectively penetrate the skin barrier to promote deep hydration, stimulate collagen synthesis, and improve skin elasticity. The presence of ferulic acid, a potent antioxidant, aids in neutralizing free radicals and protecting skin from environmental stressors, including oxidative stress and UV radiation. Organic acids such as lactic, citric, and malic acids contribute to mild exfoliation and pH balance. Additionally, the extract exhibits inhibitory effects on elastase, an enzyme linked to collagen degradation, and tyrosinase, which is involved in melanin production, thereby supporting anti-aging and brightening benefits. The fermentation process itself helps break down potential irritants, contributing to a generally milder, more stable formulation.

Stability
Fermentation processes generally yield more stable, pH-balanced formulations. While a specific optimal pH range for this extract's stability isn't explicitly detailed, protein extraction from Rhizopus oryzae fermented rice bran has been observed at alkaline pH (9.5).
Conflicts
- May present sensory challenges, such as odor, which require careful consideration during product development.
- Compatibility with specific preservative systems should be evaluated to ensure formulation stability and efficacy.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) and Scientific Committee on Consumer Safety (SCCS) have not formally reviewed RHIZOPUS/RICE FERMENT EXTRACT. However, Rhizopus oryzae, the specific fungus used in this fermentation, holds Generally Recognized As Safe (GRAS) status by the U.S. FDA for food applications.
