Science
Mechanism of Action
This ingredient operates as a powerful antioxidant, effectively neutralizing free radicals and thus safeguarding the skin from the deleterious effects of oxidative stress. It is reported to stimulate peripheral blood flow, which contributes to improved skin vitality and a more radiant complexion. The extract further supports skin firmness, provides a soothing effect by potentially reducing inflammation, enhances microcirculation, and aids in collagen production, which can lead to a visible reduction in wrinkles and improved skin elasticity. Additionally, it functions as a skin conditioning agent, helping to restore and improve the skin's tolerance to external aggressors while mitigating dehydration.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel evaluated a related ingredient, 'Ginkgo Biloba Leaf Cell Extract,' concluding that there was insufficient data to ascertain its safety under cosmetic use conditions. Specific concerns were raised regarding ginkgolic acid content, leading to a recommendation for adherence to good manufacturing practices to control impurities. While the International Agency for Research on Cancer classified general Ginkgo biloba extract as a possible human carcinogen (Group 2B) based on certain high-dose mouse studies, the CIR Panel deemed these findings not directly relevant to its use in human cosmetics.
