PANAX QUINQUEFOLIUS EXTRACT.

Acting as a sophisticated skin-conditioning agent, Panax quinquefolius extract integrates humectant, emollient, and astringent properties to refine the complexion. Its primary mechanism involves ginsenosides, which actively shield skin cells from UVB-induced photodamage and mitigate discoloration. The extract provides robust antioxidant defense, promoting enhanced skin nutrition and metabolism through improved microcirculation. It stimulates collagen synthesis while inhibiting collagenase activity, thereby preserving skin integrity and reducing visible signs of aging. Furthermore, it inhibits tyrosinase, addressing hyperpigmentation for a brighter, more even skin tone. This extract also fortifies the skin barrier by boosting moisture retention, offers anti-inflammatory relief, and exhibits antibacterial action against *Propionibacterium acnes*. Its protective actions extend to increasing antioxidative enzyme activity, neutralizing reactive oxygen species (ROS), safeguarding keratinocytes and dermal fibroblasts from UV damage, and stimulating the endogenous production of hyaluronic acid.
