ASPERGILLUS/SACCHAROMYCES/BARLEY FERMENT EXTRACT FILTRATE.

Valuable CAS - / HUMECTANT

A sophisticated postbiotic complex derived from the dual-fermentation of Hordeum vulgare with Aspergillus and Saccharomyces. This process breaks down barley proteins into low-molecular-weight bioactive compounds, delivering intense hydration and antioxidant protection that significantly outperforms traditional humectants.

Skin-conditioning Antioxidant Humectant Soothing Barrier Support

Science

This filtrate functions through a multi-pathway approach: it stimulates fibroblast-led hyaluronic acid synthesis while inhibiting hyaluronidase and collagenase enzymes to preserve skin structural integrity. Rich in ferulic acid and beta-glucans, it neutralizes oxidative stress and modulates the skin microbiome to enhance innate barrier defenses.

Key findings

  1. 01 Demonstrated 300% superior moisture retention compared to glycerin in a 65-participant trial.
  2. 02 Provides 8-hour sustained hydration and a >10% reduction in the inflammatory marker IL-8 at 3% concentration.
  3. 03 High-dose clinical observations (10%) show significant increases in ceramide synthesis and reduced transepidermal water loss (TEWL).

Due to its efficacy at low concentrations, brands often include this at 'label-only' levels (below 0.2%). For measurable barrier repair and hydration benefits, look for concentrations between 0.5% and 3.0%.

Stability

Highly stable in aqueous solutions but thermo-sensitive; must be added during the cool-down phase (below 40°C) to prevent denaturation of fermentation metabolites.

Synergies

  • Hyaluronic Acid
  • Niacinamide
  • Ceramides
  • Ferulic Acid

Conflicts

  • Strong oxidizing agents
  • High-acid environments (pH <4.0)
  • High-alkaline environments (pH >8.0)
