Science
Mechanism of Action
This extract operates through several key pathways. Its primary active compounds, ginsenosides, function as robust antioxidants, neutralizing free radicals and shielding skin cells from environmental stressors and premature aging. It notably stimulates Type I collagen synthesis in human skin fibroblasts, partly by engaging the transforming growth factor-β (TGF-β) pathway, which is essential for maintaining skin's structural integrity. Additionally, it exhibits anti-inflammatory properties, promoting a calmer complexion, and supports barrier function to enhance skin hydration. Emerging research also indicates potential roles in regulating melanin production and offering antibacterial benefits against C. acnes.

Clinical Evidence
High confidenceFor collagen synthesis, 0.01% has shown significant efficacy. For visible wrinkle reduction, 0.05% has demonstrated positive results.
Key findings
- 01 A 0.01% concentration (100µg/mL) of Panax ginseng extract was observed to significantly increase Type I collagen synthesis by 55.1% in human skin fibroblasts.
- 02 A cosmetic formulation incorporating 0.05% ginseng extract, applied to the periocular area for 8 weeks, resulted in a significant improvement in fine lines and crow's feet.
- 03 Purified Panax ginseng leaf extracts (PGLE), rich in ginsenoside Rb3, were clinically validated to decrease the depth of deep furrows (crow's feet) over an eight-week duration.
