ASPERGILLUS/MALUS DOMESTICA FRUIT/RICE SEED FERMENT FILTRATE.

Valuable / HUMECTANT

A sophisticated bio-fermented complex that utilizes Aspergillus fungi to catalyze the breakdown of rice and apple nutrients into highly bioavailable postbiotics. This multifunctional filtrate merges the moisture-binding properties of amino acids with the brightening potential of natural organic acids and antioxidants.

Science

Mechanism of Action

This ingredient functions through enzymatic conversion; Aspergillus molds secrete proteases and amylases that transform rice proteins into Natural Moisturizing Factor (NMF) precursors like amino acids and peptides. Simultaneously, it converts apple flavonoids into quercetin aglycones—potent antioxidants—while naturally synthesizing Kojic Acid and Alpha Hydroxy Acids (Malic and Lactic) to inhibit tyrosinase activity and refine skin texture.

Key findings

  1. 01 In vitro analysis confirms significant upregulation of AQP3, Filaggrin, and HAS1 genes, directly increasing epidermal moisture and barrier protein synthesis.
  2. 02 Fermentation-derived quercetin aglycones demonstrate superior radical scavenging capacity compared to standard non-fermented botanical extracts.
  3. 03 Bio-assays indicate a measurable reduction in melanin synthesis through the competitive inhibition of tyrosinase.

Because it is a 'ferment filtrate,' brands often list it to claim 'probiotic' benefits while using concentrations below 1% where gene expression for hydration (AQP3/Filaggrin) is statistically negligible.

Stability

The filtrate is naturally acidic and may lower formula pH. It is heat-sensitive and must be incorporated during the cooling phase below 40°C to maintain the integrity of bioactive peptides and enzymes.

Synergies

  • Niacinamide (enhanced brightening)
  • Hyaluronic Acid (complementary hydration pathways)
  • Panthenol (barrier reinforcement)

Conflicts

  • Strong oxidizing agents
  • High heat (>50°C)
  • Alkaline environments (pH >8.0)
