Science
Mechanism of Action
The efficacy of Stephania Cephalantha Root Extract is largely attributed to Cepharanthine (CEP). CEP exerts its anti-inflammatory actions by activating AMP-activated protein kinase (AMPK) and inhibiting the NFκB signaling pathways. Furthermore, it actively suppresses critical inflammatory markers such as lipid peroxidation, nitric oxide production, cytokine release, and cyclooxygenase expression, thereby effectively mitigating skin inflammation.

Safety
Safety Profile
Direct safety assessments by CIR, SCCS, or FDA for cosmetic use are currently unavailable. It is important to note that some regions, such as France, prohibit the use of *Stephania cepharantha* extracts due to concerns regarding potential substitution with toxic plants containing aristolochic acids. Conversely, Cepharanthine, the isolated active component, has been safely utilized as an approved pharmaceutical in Japan since the 1950s without significant adverse effects. SkinSAFE categorizes Stephania Cephalantha Root Extract as 'Irritant Free', and INCIdecoder reports low irritancy.
