Mechanism of Action
The Microbacterium fermentation process dramatically increases the bioavailability and skin absorption of Panax Ginseng's active compounds, particularly ginsenosides, by metabolizing them into more potent, smaller molecules. This ingredient works to nourish the skin, bolstering its intrinsic resilience against environmental stressors and actively contributing to the restoration of the skin barrier. It stimulates cellular regeneration, provides robust antioxidant protection against free radicals and oxidative damage, and exhibits significant anti-inflammatory actions. Furthermore, fermented ginseng effectively inhibits melanogenesis, leading to enhanced skin brightness, and boosts anti-aging efficacy by increasing specific ginsenoside metabolites (e.g., Rg3, Rg5, Rk1, compound K). These metabolites inhibit elastase and matrix metalloproteinases (MMPs) while promoting collagen type I (COL-1) mRNA expression. A crucial aspect of its mechanism is maintaining a healthy skin microbiome equilibrium, reducing undesirable bacteria such as Cutibacterium acnes and fostering the growth of beneficial Staphylococcus epidermidis.

Key findings
- 01 A serum containing Ginseng Ferment Filtrate, dexpanthenol, and Centella asiatica was as effective as hydroquinone 4% in treating post-acne hyperpigmentation, demonstrating superior results to placebo in reducing post-inflammatory hyperpigmentation and enhancing skin brightness.
- 02 Fermented Red Ginseng (0.01%), produced with Lactobacillus brevis, significantly enhanced anti-wrinkle efficacy through elastase inhibition and improved whitening effects via tyrosinase inhibition, alongside increased antioxidant activity.
- 03 Fermented Black Ginseng (0.01%), fermented by Aspergillus niger KHNT-1, demonstrated potent anti-wrinkle benefits by inhibiting elastase and MMP-1/MMP-9, increasing COL-1 mRNA expression, and exhibited antioxidant effects by reducing reactive oxygen species (ROS) levels, in addition to inhibiting tyrosinase and melanin production.
- 04 A red ginseng formulation helped maintain skin homeostasis by improving the skin microbiome, specifically decreasing Cutibacterium acnes and increasing Staphylococcus epidermidis in subjects with low levels of S. epidermidis.

Formulation
Stability
This ingredient is water-soluble and should be incorporated into formulations at temperatures below 50°C to maintain its integrity. While related fermentation processes have been observed in pH ranges of 4-6, the specific optimal pH for the stability of the final ingredient is not precisely defined. High concentrations, potentially exceeding 30% for similar fermented ginseng products, may lead to formulation stabilization challenges.

Safety
Safety Profile
The specific ingredient, MICROBACTERIUM/PANAX GINSENG ROOT FERMENT FILTRATE, has not undergone individual safety review by CIR, SCCS, or FDA. However, related Panax Ginseng Root Extract is widely regarded as safe for cosmetic use. The CIR reviewed 'Panax spp. Root-Derived Ingredients' as safe for cosmetic use at maximum concentrations up to 0.5% in leave-on products. Notably, fermented red ginseng (at 10%) has been classified as practically non-irritating and showed a significantly reduced sensitization rate (20%) compared to its non-fermented counterpart (100%), indicating that fermentation generally enhances the safety profile. A patch test is recommended for individuals with known sensitivities to probiotics or ginseng.
