Common Name(s): Pseudoalteromonas ferment extract,pseudoalteromonas ferment extract,multi-organism postbiotic ferment,biotransformed active filtrate
CAS Number: N/a
DESCRIPTION
What It Does: Supports skin microbiome ph balance through organic acid production, delivers biotransformed actives with improved sc penetration, and provides microbiome-supportive metabolites from the multi-organism fermentation.
Why It's Used: Postbiotic ferments deliver microbiome-active benefits in a stable cosmetically preservable format โ the specific organism determines the metabolite profile providing unique functionality beyond standard lab or yeast ferments.
How It Works: Multi-organism fermentation produces organism-specific metabolite profiles: enzyme biotransformation of substrate polyphenols to bioavailable aglycones, organic acid ph support, and unique organism-derived secondary metabolites providing the specific skin conditioning and bioactivity.
