Science
Mechanism of Action
This extract revitalizes skin through several pathways. It enhances cellular nutrition and metabolism by optimizing microcirculation. Crucially, it stimulates fibroblasts to increase Type I collagen synthesis, partly via the TGF-β signaling pathway, and concurrently reduces collagen degradation by inhibiting enzymes such as MMP-1. Its potent antioxidant capacity neutralizes free radicals, safeguarding skin from environmental aggressors like UV radiation and pollution. Furthermore, its polysaccharide content strengthens the skin barrier, reducing transepidermal water loss and improving hydration. It also exhibits anti-inflammatory properties, helps diminish hyperpigmentation by reducing melanin production, and offers adaptogenic defense against urban stressors.

Clinical Evidence
High confidence0.05%
Key findings
- 01 A clinical study on human volunteers demonstrated significant improvement in fine lines and wrinkles over 8 weeks with a 0.05% concentration of ginseng extract. This study identified ginsenoside Rb3, abundant in leaves, as a key compound involved in collagen synthesis.
- 02 An in vitro study on human skin fibroblasts showed a 55.1% increase in Type I collagen synthesis when exposed to 0.01% (100 µg/mL) of ginseng extract.
- 03 An in vitro pilot study on human dermal fibroblasts determined 0.000001% (10 ng/mL) as the optimal concentration for stimulating both fibroblast proliferation and collagen synthesis.
Transparency
Dusting Analysis
Effective concentrations range from a very low 0.000001% for in vitro fibroblast stimulation to 0.05% for clinically observed anti-wrinkle effects. While the maximum safe concentration is established at 0.5%, concentrations significantly above 0.05% may not yield proportionally greater benefits, though they remain within safe usage limits up to 0.5%.
The Formula
Formulation
Stability
Ginsenosides, the primary active compounds, demonstrate optimal stability within a pH range of 6.0-8.0. Stability significantly decreases under strongly acidic conditions, such as pH 3.0.
Conflicts
- Strongly acidic pH (e.g., below 6.0) can lead to significant degradation of active ginsenosides.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Panax spp. root-derived ingredients, including Panax Ginseng Root Extract, are safe for cosmetic use up to 0.5%. Dermal studies indicate a low risk of irritation or sensitization. While no specific SCCS review for 'PANAX GINSENG BUD EXTRACT' was found, it is generally well-tolerated, though individual sensitivities may vary, making patch testing advisable.
