What it is
A natural extract derived from the red seaweed Asparagopsis armata, harvested from coastal waters. It contains bioactive compounds like polyphenols and halogenated metabolites that give it soothing and antioxidant properties.
How it works
The extract's polyphenols help neutralize free radicals that can damage skin cells, while its unique halogenated compounds are thought to reduce inflammatory signals in the skin, leading to less redness and irritation. It works best as a supporting ingredient in formulations aimed at calming sensitive or stressed skin.
Pros
