Gallic Acid description

Gallic acid is a phenolic compound found naturally in fruits (such as grape seeds), grains, and vegetables. It has potent antioxidant properties, fighting the effects of free radical damage and visibly improving signs of aging from pollution and sun damage. Studies also show that gallic acid fights factors that trigger irritation in skin and can improve areas of hyperpigmentation by interrupting melanin overproduction. In its raw form, gallic acid is a colorless or slightly yellow crystal. Usage levels of gallic acid in skin care range from 0.5–1%.
