BACILLUS FERMENT FILTRATE.

Valuable CAS - / SKIN CONDITIONING

A high-performance postbiotic ingredient derived through the fermentation of Bacillus bacteria, designed to optimize the skin's biological ecosystem. It bridges the gap between gentle enzymatic exfoliation and deep structural rejuvenation, making it a versatile asset for precision aging and microbiome health.

Postbiotic Enzymatic Exfoliant Anti-aging Sebum Regulator Microbiome Support

Science

This filtrate functions as a metabolic powerhouse, delivering a complex profile of organic acids, peptides, and enzymes to the skin. It enhances cellular energy by stimulating mitochondrial ATP production and strengthens the dermal-epidermal junction by upregulating Collagen Type IV and Elastin. Additionally, it regulates sebum production via 5-alpha reductase inhibition and provides non-mechanical resurfacing through mild enzymatic activity.

Key findings

  1. 01 A 10-week clinical study at 2% concentration demonstrated a measurable reduction in fine lines and significant refinement of skin texture.
  2. 02 In vitro testing at 0.5% showed a 16.2% inhibition of 5-alpha reductase, indicating potent sebum-regulating and scalp-health benefits.
  3. 03 Research at 5% concentration confirmed enhanced moisturization and skin-lightening effects, specifically validated for sensitive skin types.

Because it is a 'ferment,' brands often include it at trace levels (below 0.1%) for marketing claims. However, clinical data suggests that at least 0.5% is required for sebum control and 2% is necessary for visible anti-aging results.
