Science
Mechanism of Action
The extract is rich in Mycosporine-like Amino Acids (MAAs), specifically Shinorine and Porphyra-334, which act as secondary UV-absorbing pigments that convert radiation into harmless heat. Beyond UV defense, it serves as a reactive oxygen species (ROS) scavenger and modulates gene expression to upregulate extracellular matrix components like procollagen and elastin while suppressing inflammatory mediators like COX-2.

Key findings
- 01 Clinical evaluation of a 7% concentration demonstrated a standalone SPF of 9.07 ± 1.62 and a PFA of 2.43 ± 0.37.
- 02 In vitro analysis confirmed significant increases in procollagen C proteinase enhancer (PCOLCE) and elastin expression.
- 03 Wound healing assays showed accelerated cell mobility and tissue repair modulation.

Dusting Analysis
Often included at very low percentages for marketing 'marine' claims; however, a minimum of 1-2% is required for anti-aging and anti-inflammatory benefits, while up to 7% is needed for measurable UV boosting.
The Formula
Formulation
Stability
MAAs are zwitterionic and stable at room temperature, but the extract is sensitive to extreme heat and alkaline environments.
Synergies
- Broad-spectrum UV filters
- Antioxidants
- Peptides
Conflicts
- High-heat processing
- Strongly alkaline environments (pH > 8.5)
