Science
Mechanism of Action
Its high squalene content (up to 8%) mimics human sebum, effectively reinforcing the lipid barrier to prevent transepidermal water loss. The oil also offers photoprotection by neutralizing oxidative stress and modulating key signaling pathways to safeguard collagen from UV degradation.

Key findings
- 01 Topical application at 3% in a cream significantly improved skin hydration and reduced roughness in xerotic skin over 28 days.
- 02 In vitro studies demonstrate concentrations between 0.05%–0.15% counteract UVA-induced collagen inhibition, stimulate fibroblast migration, and suppress pro-inflammatory factors.
- 03 At 0.1%–0.15%, it decreased UVA-induced apoptosis in human skin fibroblasts by activating the Nrf2 antioxidant pathway and restoring vital protein expression.

The Formula
Formulation
Stability
Prone to oxidation due to high unsaturated fatty acid content, particularly linoleic acid (~40-50%). Stability is significantly enhanced through hydrogenation or co-formulation with antioxidants like Vitamin E.
Synergies
- Vitamin E (Tocopherols)
- Other antioxidants
Conflicts
- Strong oxidizing agents
- High-heat processing (unless hydrogenated)
- Long-term exposure to light/air
Safety
Safety Profile
Validated as safe by the CIR (2011) for plant-derived fatty acid oils. Its well-characterized fatty acid profile as an edible oil supports its safety for cosmetic use without concentration limits.
