Is Quercus Alba Bark Extract a Good Ingredient?

Fair, because it provides astringent, oil-reducing effects and some antioxidant activity, but human data are limited. Its tannins and other natural constituents can also be drying or irritating for sensitive skin, which keeps it from a higher rating.
