Science
Mechanism of Action
Bacillus ferments function primarily through enzymatic exfoliation, where keratinase enzymes selectively digest dead keratinocytes on the skin's surface without disrupting the underlying healthy tissue. Beyond resurfacing, it acts as a microbiome modulator by suppressing opportunistic pathogens and stimulates structural proteins like collagen and elastin, while inhibiting 5-alpha reductase to manage excess sebum.

Key findings
- 01 A 2024 study demonstrated that concentrations of 5-20% significantly improved wrinkle depth and hydration levels specifically in sensitive skin cohorts.
- 02 Research published in 2024 showed a 28.68% reduction in surface sebum after 4 weeks of twice-daily application at a 5% concentration.
- 03 Clinical trials in 2023 indicated that a 2% ferment concentration notably refined skin texture and reduced fine lines over a 10-week period.
Transparency
Dusting Analysis
While visible results for texture can be seen at 2%, many mass-market products include it at 'claim' levels below 0.5%. For therapeutic sebum control and anti-aging benefits, concentrations of 2-5% are required to ensure enzymatic activity is sufficient.
The Formula
Formulation
Stability
Highly temperature-sensitive; must be incorporated during the cooling phase (ideally below 40°C) to maintain enzymatic integrity. Raw materials typically require refrigeration.
