Science
Mechanism of Action
This extract modulates the skin's inflammatory cascade by inhibiting the production of nitric oxide (NO), prostaglandin E2 (PGE2), and key pro-inflammatory cytokines including TNF-α and IL-6. Its phytochemical profile, featuring leucodin and quercetagetin, provides a dual-action approach of neutralizing free radicals and exerting antimicrobial pressure against Gram-positive bacterial pathogens.

Key findings
- 01 In vitro screening (University of Ljubljana, 2015/2021) confirmed significant antibacterial activity and cytokine suppression at 0.05% concentration.
Transparency
Dusting Analysis
Due to a lack of robust human clinical trials and its potent ethnobotanical profile, many formulations include this extract at sub-clinical levels (below 0.05%) primarily for marketing claims rather than physiological impact.
The Formula
Formulation
Stability
Highly sensitive to thermal degradation and oxidative stress; sesquiterpene lactones may lose efficacy if exposed to high heat during the cooldown phase of production.
Synergies
- Complementary antioxidants
- Humectants
Conflicts
