Science
Mechanism of Action
The extract operates as a molecular regulator, inhibiting the phosphorylation of signaling molecules like MAPKs and NF-κB to arrest the release of pro-inflammatory cytokines (TNF-α, IL-6, and PGE2). Its bioactive flavonoids, eupatilin and jaceosidin, provide rigorous antioxidant protection, while its unique polysaccharides stimulate endogenous ceramide synthesis to restore the lipid barrier.

Key findings
- 01 Yun et al. (2016) found that concentrations as low as 0.1% significantly reduced TNF-α and IL-6 levels in contact dermatitis models.
- 02 Reinhardt et al. (2019) established an IC50 of 16.2 μg/mL for the inhibition of T-lymphocyte proliferation, confirming potent immunosuppressive activity.
- 03 Supplier trials indicate that usage levels between 1% and 5% are optimal for promoting collagen synthesis and radical scavenging.
Transparency
Dusting Analysis
While biological activity is observed at 0.1%, significant barrier restoration and collagen-boosting benefits are rarely achieved below 0.5%. Formulations featuring this ingredient at the bottom of the INCI list (below 0.1%) are likely utilizing it for marketing claims rather than physiological impact.
The Formula
Formulation
Stability
Thermolabile; the extract must be incorporated during the cooling phase (below 40°C) to maintain the integrity of its volatile oils and flavonoids.
Synergies
- Ceramides
- Panthenol
- Centella Asiatica
- Niacinamide
Conflicts
- Strong oxidizing agents
- Highly acidic environments (pH < 3.0)
Safety
Safety Profile
Generally recognized as safe (GRAS) in traditional contexts; however, inhalation risks in sprayable formats limit concentrations to 0.1% in those specific deliveries.
