Science
Mechanism of Action
The combined Panax Ginseng Root and Liriope Muscari Extract acts as a multifaceted skin conditioner and emollient. It enhances the skin barrier by filling intercorneocyte gaps, thereby improving hydration and offering protection against inflammation. Panax Ginseng Root Extract specifically boosts microcirculation and skin metabolism, providing potent antioxidant protection through its ginsenoside content. It also plays a role in collagen synthesis, guards against environmental stressors, and supports skin regeneration. Liriope Muscari Extract complements these actions with its rich content of polysaccharides, flavonoids, and mucilages, contributing significant hydrating, soothing, and protective properties to the skin.

Key findings
- 01 A lotion containing 0.05% Panax ginseng leaf extract, applied to the periorbital region over eight weeks, significantly reduced the depth of deep furrows and improved overall skin wrinkle parameters.
- 02 Topical application of ginseng root boosts skin hydration, diminishes rough texture, helps fade uneven skin tone, and visibly improves wrinkles by enhancing the skin's natural firmness.
- 03 Ginseng extract has been shown to increase anti-oxidative enzyme activity, inhibit reactive oxygen species (ROS) formation, promote collagen synthesis, reduce skin wrinkles, protect keratinocytes and dermal fibroblasts from UV damage, and inhibit melanin production for a brightening effect.

Dusting Analysis
The maximum safe concentrations for Panax ginseng root extract vary significantly by type (0.04% for white Panax ginseng root extract and 0.003% for red Panax ginseng root extract in leave-on products). While general efficacy claims for ginseng root are established, specific effective concentrations for the root extract itself are often not quantified in clinical studies. The one specific efficacy concentration cited (0.05% for Panax ginseng *leaf* extract) exceeds the safe maximum for white ginseng *root* extract, creating a potential for 'dusting' if manufacturers use root extract at concentrations within safe but potentially sub-optimal ranges while implying benefits seen with higher, unspecifed root concentrations or from leaf extracts. Concentrations at or below the red flag percentage of 0.003% for red ginseng root extract should be critically evaluated for claims of significant efficacy.

Formulation
Stability
For optimal stability of ginsenosides Rg1 and Rb1 in red ginseng extract, a pH of 6.0 is recommended. The extract should be incorporated into formulations when the temperature is below 50°C to preserve ingredient integrity.
Safety
Safety Profile
Panax Ginseng Root/Liriope Muscari Extract is generally well-tolerated and considered safe for cosmetic use by the CIR Expert Panel. The maximum recommended concentration for white Panax ginseng root extract in leave-on products is 0.04%, and for red Panax ginseng root extract, it is 0.003% in leave-on and rinse-off products. Individuals with plant allergies or extremely sensitive skin should exercise caution.
