Science
Mechanism of Action
This extract operates through a triple-action pathway: it delivers high concentrations of Selenium and Vitamin E to neutralize free radicals, inhibits elastase activity by up to 62.67% to preserve tissue elasticity, and supplies essential oleic and linoleic fatty acids to reinforce the lipid bilayer and mitigate trans-epidermal water loss.

Key findings
- 01 In vitro testing demonstrated that the extract itself possesses an SPF of 20.0 and can enhance the SPF of a final formulation by approximately 100%.
- 02 Clinical application within a multi-ingredient complex resulted in a 1.793% improvement in elasticity and a 2.488% reduction in visible sagging within 24 hours.

Dusting Analysis
Due to its high fatty acid and mineral profile, this ingredient is often included at sub-therapeutic levels (under 0.1%) for marketing purposes ('label dressing'). To achieve the reported elastase inhibition and barrier restoration, higher concentrations are preferred.

Stability
The extract remains stable at temperatures up to 80°C for short intervals; however, prolonged exposure to heat above 60°C may degrade its phenolic antioxidants. High-pressure processing may alter the distribution of its protein-lipid complexes.
