Science
Mechanism of Action
This extract primarily acts by inhibiting melanogenesis through the downregulation of MITF and tyrosinase expression, a process largely mediated by JNK/MAPK phosphorylation. It significantly protects melanocytes from oxidative stress by scavenging reactive oxygen species (ROS) and preventing H2O2-induced cell death, while concurrently activating autophagy to maintain cellular homeostasis. The extract's rich content of saponins and polysaccharides also contributes to anti-inflammatory effects and supports enhanced skin texture, elasticity, tone, and compactness.

Key findings
- 01 In vitro studies on Melan-a cells demonstrated that Codonopsis pilosula extract (often studied interchangeably) at concentrations of 100-300 μg/mL significantly reduced melanin production. A concentration of 300 μg/mL exhibited an effect comparable to 100 μM arbutin in diminishing melanin. The extract also protected against H2O2-induced oxidative stress by inhibiting cell death, maintaining cell viability, and activating autophagy for cytoprotection.
