- As the name implies, antioxidants are substances that are capable of counteracting the damaging, but normal, effects of the physiological process of oxidation in animal tissue. Antioxidants are nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions).They are believed to play a role in preventing the development of such chronic diseases as cancer, heart disease ,stroke, Alzheimer's disease, Rheumatoid arthritis, and cataracts.xidative stress occurs when the production of harmful molecules called free radicals is beyond the protective capability of the antioxidant defenses. Free radicals are chemically active atoms or molecular fragments that have a charge due to an excess or deficient number of electrons.

Antioxidants Antioxidants, such as vitamins C and E, and carotenoids, may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans. Plant-based foods are the best sources.

Antioxidant An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. In turn, these radicals can start chain reactions.When the chain reaction occurs in a cell, it can cause damage or death to the cell.ntioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid (vitamin C), or polyphenols.

Antioxidants in Cosmetic Formulations Antioxidants — Playing the star and supporting roles in cosmetic formulations. As a cosmetic chemist, I love it when an ingredient is multi-functional because I can get more benefits without increasing the cost of my formula. Anti-oxidants are a great example.kin aging is accelerated by an accumulation of ROS induced damage to organic molecules like lipid, proteins and nucleic acids. The skin has its own antioxidants and defense mechanisms to neutralize ROS, including enzymes like superoxide dismutase (SOD).
