Science
Mechanism of Action
This ingredient primarily functions through its bioactive compounds, notably ginsenosides, which act as powerful antioxidants to neutralize free radicals and protect against environmental damage. It actively stimulates skin regeneration, leading to improved texture and elasticity, and strengthens the skin's natural barrier. Furthermore, it aids in reducing inflammation, boosts hydration, and optimizes skin nutrition and metabolism by enhancing subcutaneous capillary blood circulation and adjusting the skin's water balance. At a cellular level, it promotes collagen synthesis via the activation of transforming growth factor-β (TGF-β) in human skin fibroblast cells and prevents collagen destruction. It also offers protection against UV-induced damage, inhibits melanin production for a brightening effect, and encourages skin renewal by inducing the differentiation of dermal papilla cells.

Key findings
- 01 A purified extract from Panax ginseng leaves, standardized to specific ginsenoside concentrations (Rb3 ≥ 55%, Rb2 ≥ 12%), demonstrated a significant reduction in deep furrow depth in crow's feet wrinkles over an eight-week clinical period, without inducing primary skin irritation.

The Formula
Formulation
Stability
The active ginsenosides are extremely susceptible to thermal degradation during drying, storage, heating, and extraction processes. They exhibit instability in acidic conditions, with optimal stability for key ginsenosides (Rg1 and Rb1) identified at approximately pH 6.0, extending to pH 7.4 in alkaline and phosphate buffer systems.
Conflicts
- strong acids
- high heat processing
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has assessed Panax spp. root-derived ingredients as safe for cosmetic use, a direct safety review for 'PANAX GINSENG LEAF/STEM POWDER' or its specific extract is not available. However, clinical studies have shown no primary skin irritation in humans, suggesting it is generally safe and well-tolerated.
