Science
Mechanism of Action
Panax Ginseng Root Powder, primarily recognized for its active extract forms, delivers a rich complex of antioxidant compounds, including flavonoids and B vitamins. These components robustly defend the skin from external aggressors and oxidative stress. It exhibits significant anti-inflammatory properties, effectively calming the skin and reducing visible signs of puffiness, redness, itching, and general irritation. Moreover, ginseng enhances skin hydration, leading to a smoother texture, and significantly contributes to the visible reduction of wrinkles by boosting natural collagen synthesis and improving skin elasticity. Its mechanism includes inhibiting collagenase (an enzyme responsible for collagen breakdown) and stimulating pro-collagen Type I production, while activating the TGF-β signaling pathway to maintain structural integrity. For skin tone, it inhibits tyrosinase, the enzyme crucial for melanin production, thereby aiding in the lightening of hyperpigmentation and brightening the overall complexion. It also supports skin's microcirculation, optimizing the delivery of oxygen and vital nutrients to skin cells. Furthermore, Panax ginseng promotes wound healing, induces the differentiation of dermal papilla cells, and stimulates overall skin renewal, contributing to a more robust skin barrier and balanced sebum levels.
Research
Clinical Evidence
Medium confidenceEfficacious concentrations for Panax Ginseng Root Extract, which is derived from this powder, are typically within the range of 0.000002% to 0.5% in cosmetic formulations. A maximum concentration of 0.5% has been reported for Panax Ginseng Root Extract in leave-on products.
Key findings
- 01 Ginseng leaf extract (containing ginsenoside Rb3) at a concentration of 100 µg/mL significantly increased Type I collagen synthesis by 55.1% in human dermal fibroblast cells.
- 02 Ginseng berry marc extract showed a dose-dependent improvement in in vitro wound healing in keratocytes when applied at concentrations of 2.5, 5, and 10 mg/mL.
- 03 A 2020 study involving 23 participants demonstrated that an 8-week, twice-daily application of a fermented black ginseng cream resulted in noticeable skin lightening effects.
- 04 An enzyme-modified ginseng extract (EG) cream significantly reduced various parameters of eye-wrinkle formation, including total roughness and smoothness depth, in 23 human subjects.

Dusting Analysis
While Panax Ginseng Root Powder is the raw ingredient, much of the robust clinical efficacy data pertains to standardized Panax Ginseng Root Extracts, which are concentrated forms of its active compounds. The lowest reported effective concentration for these extracts is 0.000002%. Given that powder requires processing to release active components, a raw powder would typically necessitate a significantly higher concentration to deliver comparable active principles. Therefore, concentrations of Panax Ginseng Root Powder below the 0.000002% threshold (for its extract form), and particularly below 0.000001%, would likely be considered 'dusting' and yield minimal to no discernible benefits.
The Formula
Formulation
Stability
The optimal pH range for Panax Ginseng Root Extract stability is between 4.0 and 6.5. This ingredient can be successfully incorporated into an emulsion during the cool-down phase of formulation or directly into the water phase if a cold-processing method is utilized.
Safety
Safety Profile
The CIR Expert Panel has thoroughly reviewed and concluded that Panax Ginseng Root, including its powder, extract, and water derivatives, is safe for use in cosmetic and personal care products. Dermal studies consistently indicate that ingredients derived from Panax ginseng roots are not irritants or sensitizers. The maximum reported concentration for Panax Ginseng Root Extract in leave-on cosmetic formulas is 0.5%.
