BACILLUS FERMENT.

Valuable / SKIN CONDITIONING

A high-performance biotech ingredient derived through the fermentation of Bacillus bacteria, offering a non-acidic alternative to traditional chemical exfoliation. This multifunctional ferment acts as a biological catalyst that refines texture while simultaneously fortifying the skin's living ecosystem.

Summary

Enzymatic exfoliant Skin conditioning agent Humectant Microbiome support

Science

Mechanism of Action

It utilizes specialized bacterial protease enzymes to perform keratolytic exfoliation, selectively breaking the protein bonds between dead surface cells to promote cellular turnover without the irritation often associated with AHAs. Beyond exfoliation, it functions as a postbiotic to balance the microbiome, enhances the bioavailability of other nutrients, and stimulates Type IV collagen and elastin to structurally reinforce the dermal-epidermal junction.

Key findings

  1. 01 A 10-week clinical assessment of a 2% concentration demonstrated a 25.1% increase in hydration, 14.2% improvement in skin texture, and a 12.1% boost in elasticity.
  2. 02 In-vivo testing at 1% concentration over 14 days confirmed significant sebum regulation and a visible reduction in cutaneous redness.
  3. 03 Higher concentrations (up to 20%) in mixed-culture trials showed profound wrinkle depth reduction and brightening effects, even in sensitive skin cohorts.

Because it is a 'ferment,' many brands include it at sub-clinical levels (<1%) to claim microbiome benefits on the label. However, significant enzymatic exfoliation and structural anti-aging results require at least 1-2%.
