Science
Mechanism of Action
It functions as a 'tensioning agent' by stimulating the expression of Tensin-1 within fibroblasts, which enhances skin firmness and smooths fine lines. Its high concentration of terpenes (limonene, phellandrene, and elemol) provides an antimicrobial barrier (MIC 3.0 mg/mL) and suppresses pro-inflammatory cytokines such as IL-1β and TNF-α to mitigate oxidative stress.
Research
Clinical Evidence
Medium confidence0.5%
Key findings
- 01 Accelerated wound closure and complete re-epithelialization by day 16 through caspase-3 modulation (J Herbmed Pharmacol, 2026).
- 02 Dose-dependent reduction of UVB-induced pro-inflammatory markers (IL-6, TNF-α) in epithelial models (Molecules, 2022).
Transparency
Dusting Analysis
Often included at negligible levels (below 0.05%) for its masking fragrance properties rather than its biological firming or healing benefits, which require concentrations closer to the 0.5% threshold.
The Formula
Formulation
Stability
Highly susceptible to thermal degradation and oxidation; must be processed at low temperatures and stored away from direct light.
Synergies
- Tocopherol
- Retinoids
- Barrier-repair lipids
Conflicts
- High-heat processing
- Strong oxidizing agents
Safety
Safety Profile
Limited to 0.8% by IFRA standards to prevent skin sensitization; concentrated forms are classified as potential irritants (R 36/38).
