BACILLUS FERMENT FILTRATE EXTRACT.

Valuable / SKIN PROTECTING

A high-performance postbiotic metabolite obtained through the fermentation of Bacillus bacteria, engineered to harmonize the skin's microbiome while providing structural support. This multifunctional extract bridges the gap between biological blemish control and advanced age-management by optimizing the skin's surface environment.

Science

This filtrate functions via four primary pathways: it exerts antimicrobial pressure against C. acnes and S. aureus by lowering local pH and disrupting protective biofilms; it inhibits 5-alpha reductase to regulate sebum production; it provides enzymatic protection by blocking collagenase and hyaluronidase to prevent protein degradation; and it acts as a potent antioxidant that shields dermal fibroblasts from oxidative stress.

Key findings

  1. 01 A 3-week comparative trial demonstrated that a 2% concentration achieved a 63% reduction in open comedones, matching the efficacy of 2.5% benzoyl peroxide without the associated irritation.
  2. 02 A 10-week clinical study confirmed significant visible reductions in crow's feet and fine lines, alongside measurable improvements in skin density and hydration levels.
  3. 03 Research on sensitive skin subjects using mixed-culture ferments (5-20%) showed significant enhancements in skin-lightening and moisturization markers.

While this ingredient provides basic skin conditioning at low levels, the specific anti-acne and anti-wrinkle clinical benchmarks are established at 2%. Formulae containing less than this amount may claim 'probiotic benefits' without delivering the therapeutic results seen in peer-reviewed literature.

Stability

Highly resilient to thermal processing (stable up to 90°C). While stable across a broad pH range (2.0–8.0), it reaches peak bioactivity within the skin's natural acidic physiological range.

Synergies

  • Niacinamide
  • Hyaluronic Acid
  • Non-anionic surfactants

Conflicts

  • Strong oxidizing agents
  • High concentrations of anionic surfactants which may denature active proteins
