What it is
Postbiotic active produced by fermenting kelp (typically Laminaria species) with specific microbial cultures; fermentation cleaves polysaccharides into smaller bioavailable fragments, generates short-chain fatty acids and amino acids with prebiotic-like effects on the skin microbiome, and concentrates mineral content including iodine, magnesium, and zinc; the fermentation process also reduces the heavy metal burden sometimes associated with raw seaweed extracts; proposed benefits include enhanced skin barrier function and a modulating effect on commensal microorganism populations.
