Quercus alba Bark Extract, derived from the inner bark of the North American white oak, is rich in tannins, flavonoids, and polyphenols, delivering robust antioxidant and astringent benefits that help enhance skin firmness, refine texture, and mitigate redness. Its astringent action tightens pores while flavonoids combat oxidative stress, supporting resilient and toned skin appearance. Moreover, its anti-inflammatory properties — historically known and substantiated for soothing irritations — offer an added layer of support for sensitized or reactive skin types.

In haircare, White Oak Bark Extract’s tannin content (approximately 10 – 20%) plays a significant role in reducing scalp oiliness, decreasing dandruff risk, and enhancing manageability by smoothing strands and reducing frizz. Flavonoids — such as quercetin — improve microcirculation in the scalp, encouraging healthier follicle function and potentially supporting stronger hair growth. These properties make it a valuable inclusion in color-protective, volumizing, and smoothing treatments.
