BACILLUS/HOUTTUYNIA CORDATA LEAF EXTRACT/VOLCANIC ASH FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

A high-performance bio-ferment that optimizes the therapeutic potential of Heartleaf (Houttuynia cordata) by processing it with Bacillus bacteria and mineral-rich Jeju volcanic ash. This precision-engineered filtrate delivers enhanced bioavailability of polyphenols and essential minerals to target hyperpigmentation and skin sensitivity.

Melanogenesis inhibitor Anti-inflammatory agent Mineral replenisher Antioxidant protector Skin conditioning agent

Science

Mechanism of Action

The fermentation process utilizes Bacillus bacteria to enzymatically break down complex Heartleaf polyphenols, such as quercitrin, into smaller molecular weights for superior skin penetration. During this process, Jeju volcanic ash (scoria) releases essential minerals like silica, calcium, and magnesium, which act as catalysts for cellular repair. The resulting filtrate inhibits melanogenesis by downregulating the Microphthalmia-associated transcription factor (MITF) and provides potent anti-inflammatory effects by suppressing nitric oxide production.

Stability

The ingredient is stable in aqueous systems but highly thermosensitive; it must be incorporated during the cooling phase below 40°C to prevent the degradation of bioactive ferment metabolites.

Synergies

  • Niacinamide (complementary brightening)
  • Hyaluronic acid (hydration delivery)
  • Ceramides (barrier repair)

Conflicts

  • High manufacturing temperatures (>40°C)
  • Strong oxidizing agents
