Sodium ascorbyl phosphate functions as an antioxidant, a substance that neutralizes free radicals, reducing the amount of damage that they can do to cells. When applied topically to the skin, sodium ascorbyl phosphate can help slow down the aging process and the formation of fine lines and wrinkles.
One of the largest benefits of sodium ascorbyl phosphate is its ability to limit oxidative stress in the body. Viewed as one of the largest contributors to aging, oxidative stress occurs when the cells of the body sustain permanent damage due to highly reactive particles known as free radicals. Contained in sunlight and in elements in the atmosphere, free radicals are constantly acting on the body, producing microscopic amounts of damage. Over time, this damage accumulates, leading to the development of signs of aging.
