Science
Mechanism of Action
This extract operates through a dual-action pathway: it neutralizes oxidative stress using a rich profile of polyphenols and flavonoids while suppressing the MAPK and NF-κB signaling pathways to downregulate pro-inflammatory cytokines like IL-6 and IL-8. Additionally, it upregulates the expression of essential barrier proteins, specifically filaggrin (FLG), loricrin (LOR), and desmoglein-1 (DSG1), to reinforce the stratum corneum.

Key findings
- 01 A 4-week human trial using 2-4% concentration demonstrated a 63.90% increase in hydration and a 21.51% reduction in Transepidermal Water Loss (TEWL).
- 02 Clinical testing at a 1% concentration showed a significant reduction in the quantity and size of blemishes in acne-prone subjects over a 14-day period.
Transparency
Dusting Analysis
While often included in 'calming' complexes, concentrations below 1% may fail to provide the significant barrier-strengthening and blemish-reducing results seen in clinical settings. Moumoujus considers anything below 1% as primarily for label claims.
The Formula
Formulation
Stability
Bioactive sesquiterpene lactones are heat-sensitive; formulation temperature must remain below 70°C. Potency is best maintained when paired with stabilizing antioxidants.
Synergies
- Ascorbic Acid
- Tocopherol
- Glycerin
Conflicts
- High temperature processing
- Strong oxidizing agents
Safety
Safety Profile
Generally recognized as safe in the EU CosIng database. While the whole extract is safe for cosmetics, the isolated compound artemisinin is often restricted to pharmaceutical use.
