Science
Mechanism of Action
This extract operates through a multi-pathway approach: it regulates epidermal lipid synthesis to reinforce the skin barrier and utilizes Mycosporine-like Amino Acids (MAAs) to absorb UV radiation. Its high polysaccharide content acts as a film-forming humectant, while its mineral profile catalyzes enzymatic reactions necessary for collagen production and healthy cell division.

Dusting Analysis
Due to its 'marine' marketing appeal, it is frequently included at negligible concentrations (below 0.1%) to justify label claims without providing the 2% concentration typically required for significant barrier and mineral support.
The Formula
Formulation
Stability
Generally stable in aqueous systems; should be added during the cooling phase of emulsions to preserve bioactive minerals and vitamins.
Synergies
- Hyaluronic Acid
- Peptides
- Vitamin E
Safety
Safety Profile
While the CIR has requested more systemic toxicity data, it is currently used safely in leave-on products up to 2%. Users with specific marine allergies should exercise caution.
