Science
Mechanism of Action
Operates as a cellular modulator by activating the Aryl Hydrocarbon Receptor (AHR) and the OVOL1 transcription factor, which directly triggers the synthesis of filaggrin (FLG) and loricrin (LOR). Beyond protein scaffolding, it suppresses the NF-κB inflammatory pathway and enhances antioxidant enzymes such as heme oxygenase 1 to neutralize oxidative stress.

Clinical Evidence
High confidence2%
Key findings
- 01 Demonstrated significant acceleration in wound-healing and filaggrin expression at an extraction density of 2 g/mL, maintaining a non-irritating profile (Index 0.36).
- 02 Observed dose-dependent bactericidal activity and inhibition of microbial virulence factors at concentrations between 0.4 and 3.2 mg/mL.

Dusting Analysis
As a plant-derived callus extract, it is frequently used at trace amounts for marketing purposes. However, achieving measurable upregulation of barrier proteins and antimicrobial benefits requires precise inclusion levels, typically above 0.1% of the active extract.
The Formula
Formulation
Stability
Highly stable in aqueous solutions and oil-in-water emulsions. Bioactivity is best preserved when processed via ultrasonic or high-temperature aqueous extraction to protect phenolic integrity.
Synergies
- Ceramides
- Niacinamide
- Panthenol
Conflicts
- Strong oxidizing agents
- High alkaline conditions (> pH 7.0)
Safety
Safety Profile
Classified as non-irritating based on human patch testing (Skin Irritation Index 0.36). While not yet formally reviewed by the CIR, its long history of use in East Asian skincare and low irritation profile suggest excellent safety.
