Science
Mechanism of Action
This extract stimulates the Akt and ERK 1/2 signaling pathways to trigger keratinocyte proliferation while specifically inducing Type IV collagen synthesis, reinforcing the dermal-epidermal junction. Simultaneously, it acts as an anti-inflammatory agent by suppressing COX-2 and iNOS enzymes, thereby reducing the production of redness-inducing mediators like PGE2 and pro-inflammatory cytokines.

Key findings
- 01 Demonstrated dose-dependent human keratinocyte proliferation and Type IV collagen synthesis at an EC50 of 8.5 ng/mL.
- 02 Clinical trials of related Artemisia extracts showed a significant reduction in facial redness and acne blemishes within 7–14 days at a 1.0% concentration.

Dusting Analysis
While it shows bioactivity at very low concentrations (ng/mL), many commercial formulas include it at trace levels (below 0.1%) primarily for label claims rather than therapeutic skin regeneration or anti-inflammatory results.
The Formula
Formulation
Stability
Highly temperature-sensitive; must be incorporated during the cool-down phase below 40°C to prevent degradation of volatile bioactive compounds. Solubility varies by extraction method (hydroglycolic vs. oil-based).
Synergies
- Centella Asiatica
- Panthenol
- Ceramides
Conflicts
- Strong oxidizing agents
- High heat processing
Safety
Safety Profile
While specifically not yet reviewed by CIR, taxonomic relatives are cleared for leave-on use up to 10%. It is generally well-tolerated and classified as a safe conditioning agent in the EU.
