Science
Mechanism of Action
This extract operates through a high concentration of phycocolloids and phycobiliproteins, which serve as potent radical scavengers to prevent premature cellular aging. Its polysaccharide-rich composition creates a non-occlusive, bio-mimetic film that bolsters the Natural Moisturizing Factor (NMF) and provides a significant soothing response to environmental stressors.

Dusting Analysis
Because it is a botanical extract with immediate film-forming benefits, brands often include it at negligible levels (<0.1%) just for 'marine' marketing claims. For meaningful anti-aging and antioxidant protection, concentrations closer to the 1-5% range used in clinical evaluations are required.
The Formula
Formulation
Stability
Highly sensitive to thermal degradation; should not be heated above 50°C. Peak stability of its antioxidant pigments occurs at a near-neutral pH of 6.8. Prolonged UV exposure can diminish its potency.
