BACILLUS FERMENT EXTRACT FILTRATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A high-performance postbiotic ingredient derived through bacterial fermentation, designed to provide non-acidic enzymatic exfoliation and microbiome regulation. It serves as a multifunctional bioactive that refines skin texture while strengthening the structural integrity of the dermal-epidermal junction.

Summary

Enzymatic Exfoliant Sebum Regulator Soothing Agent Microbiome Balancer Dermal Resurfacing

Science

Mechanism of Action

Operates via enzymatic proteolysis, where bacterial proteases selectively break down cell-binding proteins in the stratum corneum to facilitate gentle resurfacing. Beyond exfoliation, it acts as a 5-alpha reductase inhibitor to modulate sebum, lowers local pH to discourage pathogenic biofilms, and upregulates essential proteins like Laminin 5 and CK15 to maintain the extracellular matrix and stem cell niches.

Key findings

  1. 01 A 5% concentration demonstrated a 47% reduction in cutaneous redness and sebum secretion levels comparable to benzoyl peroxide with superior tolerability.
  2. 02 A 2% concentration increased Laminin 5 levels by 29.9% and CK15 protein expression by 276%, reinforcing the dermal-epidermal junction.
  3. 03 Mixed-culture extracts at 5-20% showed significant improvements in wrinkle depth and moisturization in sensitive skin cohorts.

Due to its complex manufacturing and marketing appeal as a 'probiotic/postbiotic' technology, it is frequently included at sub-clinical levels (<1%) for label claims. Formulations require at least 2% to achieve measurable structural benefits.
