Science
Mechanism of Action
Sargassum yezoense extract acts on the skin through several mechanisms. It provides antioxidant protection by actively scavenging free radicals and mitigating oxidative stress induced by UV exposure. Its anti-inflammatory properties soothe the skin, visibly reducing redness and irritation by attenuating inflammatory responses and suppressing inflammatory mediators. Furthermore, the extract, rich in polysaccharides, enhances skin hydration and reinforces barrier function by optimizing moisture retention. Preliminary insights suggest potential anti-aging effects via the inhibition of enzymes like collagenase, and skin brightening capabilities through tyrosinase inhibition and reduced melanin synthesis.

The Formula
Formulation
Stability
Optimal extraction conditions, such as 52.8 °C with 74.1% ethanol over 8.3 hours, are crucial for maximizing the yield of phenolic compounds and preserving heat-sensitive constituents like Sargahydroquinoic acid. Certain components, such as fucoxanthin, are notably fat-soluble.
Conflicts
- Potential general incompatibility with other ingredients due to the complex nature of seaweed extracts, which can impart distinct color and scent to formulations.
