Quercus Alba (White Oak) Bark Extract
What is Quercus Alba (White Oak) Bark Extract?
Quercus Alba Bark Extract comes from the inner bark of the white oak tree (Quercus alba), a deciduous species native to North America. This botanical extract is rich in tannins, polyphenols, and flavonoids, which are naturally occurring compounds extracted through water or solvent methods. In cosmetics, it belongs to the category of plant-derived actives commonly found in toners, cleansers, masks, and moisturizers. It functions by forming a protective film on the skin's surface through tannin-protein interactions, which temporarily tightens pores and refines texture. Additionally, its emollient properties help retain moisture, while antioxidant components neutralize free radicals, supporting overall skin resilience. The extract's mild nature makes it suitable for various formulations aiming to balance oiliness and enhance suppleness without disrupting the skin barrier.
