Science
Mechanism of Action
It downregulates key pro-inflammatory cytokines including IL-6, IL-8, and TSLP while upregulating filaggrin expression to reinforce the structural integrity of the skin barrier. Furthermore, it exhibits antimicrobial properties against acne-triggering bacteria and provides antioxidant protection via compounds like chamazulene.

Key findings
- 01 Application of 1% concentration demonstrated significant reduction in acne-related redness and symptom severity within a 14-day window.
- 02 In-vitro analysis showed effective tyrosinase inhibition at 18.1 µg/mL, suggesting a brightening potency approximately three times greater than kojic acid.
- 03 Exhibited significant collagenase inhibitory activity (IC50 of 10.38 µg/mL), highlighting its role in preserving the extracellular matrix against aging.
Transparency
Dusting Analysis
Because it is a trendy botanical, brands often include it at trace levels (below 0.1%) for marketing claims. Clinical results for barrier repair and acne reduction typically require concentrations closer to 1%.
The Formula
Formulation
Stability
Highly volatile and sensitive to photo-oxidation; must be housed in opaque, airtight packaging. Maintaining a slightly acidic environment (pH 4.0-6.5) is critical for extract stability.
Synergies
- Niacinamide
- Ceramides
- Centella Asiatica
Conflicts
- Strong oxidizing agents
- Highly alkaline formulations
Safety
Safety Profile
Contains thujone, a naturally occurring compound restricted by IFRA guidelines. While safe in topical cosmetics at low concentrations, it is generally recommended to avoid or consult a physician during pregnancy due to the neurotoxic potential of thujone at high doses.
