Science
Mechanism of Action
This ingredient operates via a dual-action pathway: the rice-derived ferment fractions stimulate the synthesis of essential ceramides and filaggrin to fortify the stratum corneum, while the biotransformed Rhinacanthus nasutus components (rhinacanthins and flavonoids) neutralize oxidative stress and downregulate tyrosinase activity to inhibit melanin production.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical testing demonstrated a 157% increase in stratum corneum ceramide content over a 4-week period, significantly enhancing barrier resilience.
- 02 Research indicates a measurable up-regulation of hyaluronan synthase 2 (HAS2) and filaggrin expression, which directly boosts natural moisturizing factor (NMF) levels and structural integrity.
Transparency
Dusting Analysis
Given its efficacy in barrier repair at 1-3%, concentrations below 0.5% are often used for marketing claims ('label dressing') without providing the measurable ceramide-boosting benefits observed in clinical data.
The Formula
Formulation
Stability
Thermolabile at high temperatures; avoid heating above 50°C to prevent protein degradation and darkening. Maintaining a stable pH within the physiological range is critical for filtrate clarity.
Synergies
- Niacinamide
- Hyaluronic Acid
- Ceramides
- Panthenol
Conflicts
- Strong oxidizing agents
- Extremely acidic formulations (pH < 3.0)
- High-proof ethanol
Safety
Safety Profile
Classified as Generally Regarded as Safe (GRAS). The fermentation process typically reduces the allergenic potential of the base botanicals, making it highly compatible with reactive skin.
