Science
Mechanism of Action
It functions as a multi-modal barrier restorer by upregulating filaggrin expression to strengthen the stratum corneum and inhibiting inflammatory cytokines such as IL-4. Additionally, it provides brightening effects by suppressing tyrosinase activity to limit melanin production and utilizes its high Vitamin E content to neutralize oxidative stress.

Clinical Evidence
High confidence1.5%
Key findings
- 01 Demonstrated a significant reduction in transepidermal water loss (TEWL) and restored barrier function in compromised skin models.
- 02 Identified as a safe and effective historical usage level for leave-on applications, maintaining a non-irritating profile.

Dusting Analysis
While often used as a carrier oil at higher percentages, it is sometimes 'dusted' in mass-market formulations at negligible amounts (<0.1%) just for label claims. For precision efficacy in barrier repair, levels near 1.5% are recommended.
The Formula
Formulation
Stability
Highly stable due to an oleic acid content of 74-87%, though it should be protected from UV exposure and extreme heat. Stability is enhanced when paired with tocopherols.
Synergies
- Tocopherol (Vitamin E)
- Chelating agents
- Ceramides
Conflicts
- Strong oxidizing agents
- Highly alkaline bases
Safety
Safety Profile
Recognized by the CIR and China's CSAR as safe for topical use; it is historically non-sensitizing even in leave-on formats.
