Science
Mechanism of Action
It functions via three primary biological pathways: suppressing NF-κB and nitric oxide to reduce inflammation, activating the NRF2 pathway for cellular antioxidant defense, and stimulating the Aryl Hydrocarbon Receptor (AHR). This receptor translocation triggers the production of essential barrier proteins, specifically filaggrin and loricrin, which seal the epidermal barrier.

Clinical Evidence
High confidence0.5%
Key findings
- 01 Statistically significant upregulation of filaggrin (FLG) and loricrin (LOR), directly improving atopic dermatitis symptoms.
- 02 Polysaccharide-rich fractions exhibited humectant properties comparable to sodium hyaluronate.

Dusting Analysis
Because biological activity is documented as low as 0.03%, many brands include it at 'trace' levels (below 0.01%) for marketing purposes. For therapeutic barrier repair and moisturizing benefits, concentrations should ideally exceed 0.03% and 2.0% respectively.
The Formula
Formulation
Stability
Highly stable in mildly acidic environments; however, phenolic content degrades rapidly in alkaline conditions (pH > 7). The extract is also sensitive to UV radiation and thermal stress.
Synergies
- Ceramides
- Sodium Hyaluronate
- Panthenol
- Niacinamide
Conflicts
- Strong oxidizing agents
- Alkaline formulations (pH > 7.5)
Safety
Safety Profile
While generally safe and non-irritating, in vitro data suggests high concentrations (>0.3% of certain raw extracts) may exhibit cytotoxicity in keratinocytes, though this rarely translates to finished topical products due to dilution and stabilization.
