Science
Mechanism of Action
With an oleic acid content ranging from 75% to 90%, it mimics the skin's natural sebum to reinforce the lipid mantle and significantly reduce transepidermal water loss. Beyond surface occlusion, it operates on a cellular level by upregulating filaggrin for barrier integrity, stimulating human type I procollagen synthesis, and inhibiting MMP-1 enzymes to prevent collagen degradation.

Clinical Evidence

Key findings
- 01 Topical application at 1% concentration demonstrated a statistically significant suppression of transepidermal water loss (TEWL) within a 2-hour window.
- 02 In vitro analysis at 0.1 mg/mL confirmed induction of type I procollagen and the inhibition of collagenase expression in dermal fibroblasts.
- 03 Concentrations between 0.1% and 0.5% showed potent anti-inflammatory activity by inhibiting NF-κB and AP-1 signaling pathways.
Transparency
Dusting Analysis
While this oil is effective at relatively low concentrations (0.5% for anti-inflammatory benefits), levels below 0.1% are generally insufficient to provide the pro-collagen or barrier-occlusive benefits typical of the ingredient.
The Formula
Formulation
Stability
Exhibits higher oxidative stability than polyunsaturated oils due to high monounsaturated fat content. Formulations should be stored in UV-protective, airtight packaging.
Synergies
- Tocopherols
- Phytosterols
- Ceramides
Conflicts
- L-Ascorbic Acid (layering high-oleic oils immediately may hinder penetration of low-pH actives; a 10-minute interval is recommended)
Safety
Safety Profile
Assessed as non-sensitizing with an EWG Hazard Score of 1. It is exceptionally well-tolerated across all demographics.
