Science
Mechanism of Action
This multi-functional ferment acts on several biological pathways: it upregulates Hyaluronan Synthase (HAS) to boost endogenous hydration, stimulates mRNA expression of crucial tight-junction proteins like ZO-1 and Claudin-1 to repair the skin barrier, and inhibits tyrosinase activity to modulate melanin production. Furthermore, its organic acid content provides antioxidant protection while promoting extracellular matrix integrity.
Research
Clinical Evidence
High confidence2.5%
Key findings
- 01 Demonstrated significant induction of hyaluronic acid production and barrier protein synthesis at 1-5% concentrations.
- 02 Inhibition of tyrosinase and melanin generation confirmed in clinical whitening evaluations at a 5% dosage.
- 03 Human dermal fibroblast protection and collagen promotion observed at 2% concentration via antioxidant pathways.
Transparency
Dusting Analysis
Due to its complex name and exotic 'J-Beauty' appeal, it is often included at minute levels (below 0.5%) for marketing claims. A minimum of 1.0% is required to trigger measurable physiological benefits for skin barrier and hydration.
The Formula
Formulation
Stability
Highly stable in aqueous systems; should be incorporated during the cooling phase (below 40°C) to maintain the structural integrity of its bioactive peptides and enzymes.
Synergies
