Science

Mechanism of Action

The efficacy of Linum Usitatissimum Seed Oil is attributed to its high content of essential fatty acids: 35-65% alpha-linolenic acid (omega-3), 11-24% linoleic acid (omega-6), and 11-35% oleic acid (omega-9). These fatty acids are integral for sustaining a robust skin barrier and reducing transepidermal water loss. Furthermore, its antioxidant compounds, including tocopherols, phytosterols, polyphenols, and flavonoids, work synergistically to neutralize free radicals, alleviate skin inflammation, and shield cells from oxidative stress.

Stability

Due to its elevated polyunsaturated fatty acid content, Linum Usitatissimum Seed Oil exhibits susceptibility to oxidation, impacting product shelf life. Optimal stability necessitates the inclusion of co-antioxidants like tocopherol and packaging in opaque, air-limited containers. Oxidative stability significantly diminishes at temperatures exceeding 110°C.
