Science
Mechanism of Action
This extract functions as a potent antioxidant, safeguarding skin from urban stressors like UV exposure and pollution through its high content of polyphenols and rhinacanthins. Its soothing action is attributed to inhibiting TNF-alpha release and preventing NF-κB activation, which diminishes oxidative stress and visible redness. Furthermore, it offers clarifying benefits via in vitro antimicrobial activity against common skin flora such as S. epidermidis and P. acnes, and exhibits additional anti-inflammatory, anti-allergic, antifungal, and antiviral properties.

Stability
Optimal formulation pH is between 4.5 and 6.5; studies indicate enhanced stability at pH 5.5 compared to higher pH levels (7.0, 8.0) in aqueous methanolic solutions. To preserve phenolic compounds and color, incorporate the extract during the cool-down phase of processing. Protect formulations from light and air. In systems using mineral-rich water, a chelator like GLDA or EDTA is recommended to maintain product clarity and aesthetic tone.
Safety
Safety Profile
A topical preparation containing a key component (rhinacanthin C) from a related species (Rhinacanthus nasutus) was proven non-genotoxic, non-skin corrosive, and non-irritating in human and animal studies, supporting a low sensitization risk. No specific Cosmetic Ingredient Review (CIR), SCCS, or FDA safety status has been established for Rhinacanthus Communis Extract itself.
