Science
Mechanism of Action
Ginkgo Biloba Leaf Powder operates as a powerful antioxidant and free radical scavenger, primarily due to its high concentration of beneficial flavonoids and terpenoids. It exerts a regulating influence on the skin's immune system, which aids in quicker inflammation resolution and helps rebalance blemished or combination skin. Its anti-inflammatory and antimicrobial actions soothe irritation, diminish redness, and can alleviate allergic responses. The ingredient enhances microcirculation by strengthening blood vessels, thereby improving nutrient delivery to the skin and counteracting edema. Furthermore, it may contribute to collagen synthesis, potentially reducing the appearance of fine lines and wrinkles while preserving skin's structural integrity. It also supports skin hydration by enhancing moisture retention and offers potential photoprotection against UV radiation through its antioxidant activity, aiding in wound healing and minimizing scarring.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Ginkgo Biloba Leaf Powder, alongside other Ginkgo biloba leaf-derived ingredients, is safe when used in current practices and concentrations, provided it is formulated to be non-sensitizing. The panel emphasized the importance of good manufacturing practices to limit ginkgolic acid impurities. While no specific maximum concentration for the powder was set by CIR, concentrations for Ginkgo Biloba Leaf Extract (GBE) have been reported up to 0.24% in leave-on manicuring preparations, 0.25% in rinse-off skin cleansing products, and up to 1% in face and neck skin preparations. There is no FDA-approved indication for oral Ginkgo Biloba, and no SCCS opinion was found regarding its cosmetic use.
