ASPERGILLUS/SACCHAROMYCES/RICE FERMENT FILTRATE.

Valuable CAS - / HUMECTANT, SKIN CONDITIONING

A sophisticated dual-fermented bioactive extract that leverages the enzymatic power of Aspergillus and Saccharomyces to refine rice proteins into highly bioavailable nutrients. This nutrient-dense filtrate serves as a multifaceted skin-restructuring agent, delivering deep hydration while simultaneously targeting the structural integrity of the dermal matrix.

Humectant Skin Conditioning Agent Barrier Repair Anti-aging Brightening

Science

Mechanism of Action

This ingredient functions by supplying a complex array of fermentation-derived metabolites, including amino acids, organic acids, and vitamins, which act as biological signals to upregulate barrier proteins like Filaggrin and Aquaporin-3. On a deeper level, it mitigates oxidative stress from UVA exposure and stimulates fibroblasts to increase the synthesis of Collagen types I and III, alongside Elastin, for improved skin elasticity.

Key findings

  1. 01 In vitro modeling at 1.25% demonstrated a 26.93% increase in epidermal water content and enhanced barrier protein expression.
  2. 02 A 3% concentration resulted in a significant upregulation of dermal mRNA levels: Collagen Type I (+17%), Type III (+47%), and Elastin (+159%).
  3. 03 Even at trace amounts (0.0142%), the filtrate showed an 18.38% reduction in melanin content, indicating notable brightening potential.

Due to its high cost and the popularity of 'ferment' marketing, many products include this ingredient at trace levels (below 0.1%) to claim its benefits. However, clinical data suggests that a minimum of 1.25% is required for significant barrier improvement and 3% for meaningful anti-aging structural changes.
