BIFIDA/ENTEROCOCCUS FAECIUM/LACTOBACILLUS/STREPTOCOCCUS THERMOPHILUS/SOYMILK FERMENT EXTRACT.

Essential

A sophisticated multi-strain probiotic complex derived from the fermentation of soymilk using four distinct bacterial cultures. This bio-active extract serves as a comprehensive microbiome-support agent, delivering postbiotic metabolites that reinforce the skin's natural defense systems and moisture retention capabilities.

Microbiome Modulator Barrier Repair Agent Humectant Anti-inflammatory Skin Protectant

Science

This extract operates through precision bio-conversion: the four-strain bacterial consortium metabolizes soy proteins into bio-available small-chain peptides and transforms soy isoflavones into potent aglycones like genistein and daidzein. These bio-actives stimulate the endogenous production of collagen and essential ceramides, while the resulting lactic acid and exopolysaccharides optimize the skin's pH and competitively exclude harmful pathogens.

Key findings

  1. 01 Application at 10% concentration demonstrated significant enhancement of the cutaneous barrier and a marked reduction in sensitivity for reactive skin types.
  2. 02 A 5% concentration showed superior efficacy in decreasing acne-related inflammation and lesion size compared to traditional antimicrobial agents.
  3. 03 Consistent use of 1-5% concentrations resulted in measurable improvements in skin resilience and structural integrity over a 28-day period.

Due to its long INCI name and high manufacturing cost, this ingredient is frequently 'label-dusted' at concentrations below 0.5%. However, clinical data suggests that a minimum of 1% is required for barrier support, with 5% being the target for therapeutic anti-inflammatory benefits.
