Science
Mechanism of Action
This extract derives its efficacy from a rich profile of antioxidants, notably flavonoids (including quercetin, kaempferol, and ginkgetin) and terpenoids. These compounds meticulously protect dermal cells from oxidative stress induced by free radicals from UV exposure and pollution, thereby combating premature aging and preserving collagen integrity. It demonstrates significant anti-inflammatory capabilities, effectively calming irritated skin, reducing redness, and alleviating symptoms associated with inflammatory conditions like acne, rosacea, and eczema. The extract enhances cutaneous microcirculation, facilitating superior oxygen and nutrient delivery to cells, which promotes healthy cell turnover and contributes to a more luminous appearance. Moreover, it supports the intrinsic production of collagen and elastin, leading to improved skin elasticity and firmness while diminishing the visibility of fine lines and wrinkles. It aids in skin regeneration and repair processes, assisting in the replacement of damaged cells and potentially accelerating wound healing. Additionally, Ginkgo Biloba Nut Extract enhances the skin's capacity to retain moisture, contributing to sustained hydration, and exhibits antibacterial activity against certain skin-harming bacteria. There is also preliminary indication that it may offer a skin lightening effect by inhibiting tyrosinase, an enzyme crucial for melanin synthesis.
