Science

Mechanism of Action

This extract's efficacy stems from its complex blend of bioactive compounds, notably Polyunsaturated Fatty Acids (PUFAs) like Eicosapentaenoic Acid (EPA), various carotenoids (e.g., astaxanthin, β-carotene, zeaxanthin), and phenolic compounds. These constituents collectively provide comprehensive skin benefits, functioning as potent antioxidants, mitigating inflammation, and exhibiting anti-melanogenic effects. It significantly enhances skin hydration by acting as a humectant through its polysaccharides and by upregulating Hyaluronan Synthase 2 (HAS-2) expression, which is crucial for intrinsic hyaluronic acid synthesis. Furthermore, the extract supports cellular renewal, contributes to skin re-mineralization, and helps protect against oxidative stress and DNA damage, while positively modulating genes associated with skin texture, hydration, and reduced irritation.
