Hydrating Barrier Support Anti-aging Skin Brightening Antioxidant Gentle Exfoliation Anti-inflammatory Conditioning

Science

Mechanism of Action

This ferment extract delivers a synergistic blend of skin-beneficial compounds including amino acids, organic acids (like lactic acid), peptides, polyphenols (such as ferulic acid), gamma-aminobutyric acid (GABA), vitamins (e.g., niacin), and ceramides. Amino acids replenish the skin's Natural Moisturizing Factor (NMF), attracting and retaining vital moisture. Lactic acid offers mild surface exfoliation and helps maintain optimal skin pH. Peptides contribute to improved hydration and stimulate collagen production, bolstering skin elasticity. The extract also exhibits potent antioxidant activity by reducing reactive oxygen species (ROS), calms inflammation, encourages fibroblast proliferation for anti-aging benefits, and helps reduce melanin synthesis for a brighter complexion. Furthermore, it upregulates key moisturizing and barrier proteins/genes such as Aquaporin 3 (AQP3), Filaggrin (FLG), Hyaluronan Synthase 1 (HAS1), Claudin 1 (CLDN1), Involucrin (IVL), and Zonula Occludens-1 (ZO-1).

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has issued an Insufficient Data Announcement (IDA) for broad 'Yeast-Derived Ingredients,' lacking specific review for 'Rhizopus/Rice Ferment Extract Filtrate'. While specific safety data for this exact ingredient by CIR or SCCS is absent, fermented rice ingredients are generally perceived as mild, and the fermentation process itself can reduce potential irritants, contributing to a low irritancy potential.
