Science
Mechanism of Action
This ingredient functions as a structural fortifier by providing orthosilicic acid, a bioavailable form of silica that facilitates collagen cross-linking and strengthens connective tissues. During fermentation, Bacillus bacteria release proteolytic enzymes that gently refine skin texture, while simultaneously breaking down complex botanical polysaccharides into low-molecular-weight Natural Moisturizing Factors (NMFs). Furthermore, high concentrations of caffeic acid deliver a robust antioxidant shield, neutralizing oxidative stress at the cellular level.

Clinical Evidence
High confidence0.4%
Key findings
- 01 A 2021 CIR safety assessment confirmed that a 0.4% concentration in leave-on formulas passed Human Repeated Insult Patch Tests (HRIPT) on over 200 subjects with zero sensitization.
- 02 In vitro analysis at 25 μg/ml demonstrated a measurable reduction in lipid peroxide levels, highlighting significant antioxidant capacity.
- 03 Oral toxicity benchmarks for the substrate plant indicate a No-Observed-Adverse-Effect Level (NOAEL) of 3.0%, reinforcing its high biological safety profile.
Transparency
Dusting Analysis
Due to its premium fermentation process, this ingredient is frequently used at 'claim levels' (below 0.1%). To achieve measurable improvements in skin density and antioxidant defense, it should ideally be formulated near its 0.4% safety-tested maximum.
The Formula
Formulation
Stability
Exhibits excellent stability in aqueous systems and emulsions; the fermentation process inherently protects phenolic acids from rapid oxidation compared to raw extracts.
Synergies
- Vitamin C
- Peptides
- Hyaluronic Acid
Conflicts
- Strong oxidizing agents
- pH levels below 3.5 (which may precipitate silica components)
Safety
Safety Profile
Safety is inferred from the parent Equisetum Arvense extract and the well-documented profile of Bacillus-derived ferments in topical applications.
