Common Name(s): Bifida ferment lysate,postbiotic ferment,bioactive metabolite complex
CAS Number: N/a
DESCRIPTION
What It Does: Supports skin microbiome balance, delivers anti-inflammatory postbiotic metabolites, and provides biotransformed botanical actives with 10โ50ร improved sc penetration versus native glycoside forms.
Why It's Used: Preferred over live probiotic formats for conventional cosmetic stability and preservation compatibility, while delivering equivalent microbiome-supportive postbiotic metabolites.
How It Works: Multi-organism fermentation produces organic acids (acidifying skin surface ph to 4.5โ5.5), bacteriocins, and ฮฒ-glucosidases that deglycosylate botanical polyphenols to their more penetrant aglycone forms. tlr2-active cell wall fragments train skin immune cells toward anti-inflammatory tolerance.
