Science
Mechanism of Action
This extract triggers the biological synthesis of essential structural proteins, including filaggrin and loricrin, while simultaneously boosting the production of epidermal lipids like ceramides and cholesterol. By suppressing the NF-kB pathway, it inhibits pro-inflammatory cytokines (TNF-alpha, IL-1, IL-6) and regulates sebum production to maintain a balanced microbiome.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 In-vivo analysis showed an 18.6% reduction in Transepidermal Water Loss (TEWL) and significant mitigation of redness and scaling over 28 days.
- 02 Clinical testing confirmed increased synthesis of barrier-forming lipids (ceramides) and structural proteins to restore epidermal integrity.
- 03 Research models demonstrated accelerated re-epithelialization and fibroblast proliferation at concentrations as low as 0.2%.
Transparency
Dusting Analysis
While often included in 'botanical blends' at negligible levels (<0.1%), clinical efficacy for barrier restoration and sebum regulation is typically documented between 1.0% and 3.0%.
The Formula
Formulation
Stability
Highly susceptible to photo-oxidation and degradation due to its terpene profile; must be housed in UV-protective, opaque packaging. Stable across a broad pH spectrum (2.0-10.0) in specific preparations.
Synergies
- Ceramides
- Niacinamide
- Squalane
Conflicts
- Strong oxidizing agents
- Mineral acids
- Strong reducing agents
Safety
Safety Profile
Recognized as FDA GRAS for consumption. However, the presence of natural limonene (up to 79%) and linalool requires careful concentration management to avoid potential sensitization in reactive individuals.
