Science
Mechanism of Action
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.
Research
Clinical Evidence
High confidence2%
Key findings
- 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.
- 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.
- 03 Research on sensitive skin subjects using mixed-culture ferments (5-20%) showed significant enhancements in skin-lightening and moisturization markers.

Dusting Analysis
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.
The Formula
Formulation
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
Safety
Safety Profile
Confirmed as a non-irritant through Repeated Insult Patch Testing (RIPT). It is widely recognized as a safe, soothing alternative to traditional harsh anti-acne actives.
