Science
Mechanism of Action
The extract operates through a high concentration of flavonoids and phenolic compounds that neutralize free radicals via electron donation. It simultaneously modulates the inflammatory response by downregulating key cytokines like IL-1α and TNF-α, while its mineral content supports osmotic balance and barrier hydration.

Key findings
- 01 In vivo testing at 0.5% in a specialized blend confirmed significant improvements in skin homogeneity and a visible reduction in signs of fatigue around the periorbital area.
- 02 A 4-week clinical trial involving 30 subjects demonstrated that aqueous leaf extracts significantly enhance complexion radiance and tone uniformity.
- 03 In vitro assays verified broad-spectrum antimicrobial activity against S. aureus at concentrations between 50-200 mg/ml.

Dusting Analysis
While many brands claim 'Red Pepper' benefits, they often include it at negligible levels for marketing. Clinical efficacy for radiance is documented at 0.5%; concentrations significantly below this likely provide only basic antioxidant support rather than visible brightening.
The Formula
Formulation
Stability
Highly stable in water-based systems, especially when stabilized with humectants like glycerin to improve molecular delivery and shelf life.
Synergies
- Glycerin
- Vitamin C
- Niacinamide
Conflicts
