Mechanism of Action
This extract, abundant in bioactive ginsenosides (such as F2, Rb3, and Rb2), acts as a potent antioxidant by inhibiting Reactive Oxygen Species (ROS) and boosting natural anti-oxidative enzymes, thus safeguarding skin from environmental damage. It also exhibits anti-inflammatory properties, providing a soothing effect. Key to its age-defying action, Panax Ginseng supports collagen integrity and synthesis by suppressing collagenase, an enzyme responsible for collagen breakdown, and stimulating transforming growth factor-β (TGF-β) in human dermal fibroblasts. This multifaceted action improves skin firmness, elasticity, and diminishes the appearance of wrinkles. Furthermore, it aids in skin brightening through tyrosinase inhibition, reducing hyperpigmentation, while also enhancing hydration, strengthening the skin barrier, and promoting microcirculation for improved nutrient delivery and regeneration.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Panax spp. root-derived ingredients safe at their current uses and concentrations. While generally well-tolerated, rare instances of allergic reactions, skin rashes, itching, or irritation may occur with topical application, suggesting a patch test for individuals with sensitive skin. The FDA does not typically 'approve' cosmetic ingredients, though product listings may reference 'FDA Standard'. A max concentration of 0.1% has been noted for related Panax ginseng root extract in some historical uses.
