Antioxidants very useful active ingredients for the manufacturing of cosmetics. Generally, antioxidants interrupt oxidation reactions and prevent the effects of oxygen radicals (e.g. peroxides) both processes known to damage the integrity and function of various natural substances. Antioxidants are useful in two ways: On the one hand they prevent degradation of natural ingredients (proteins, sugars, lipids) in the cosmetic product. On the other hand antioxidants protect the skin cells from being damaged and slow down the aging process. Antioxidants have been shown to boost the skin's radiance, minimize age spots, sun spots, and fine lines.
