Oxidation occurs every day as part of our metabolic functioning and it has an important role to play in overall health. But oxidation also unleashes free radicals, which damage healthy cells.

Free radicals occur in greater numbers after the skin is exposed to UVA and UVB rays, pollution or when the skin experiences minor trauma. Our susceptibility to them is heightened if we are stressed, smoke, eat poorly or don’t allow ourselves sufficient rest.

Anti-oxidants are found in a variety of foods, and bring health benefits by neutralising free radicals. Polyphenolic anti-oxidants are found in coffee, chocolate, red wine, soy, oregano and olive oil; flavonoids in tea, citrus fruits, onion and apple; and lycopene in tomatoes and grapefruit.

Since anti-oxidants in tablet form have been shown to be less effective than those consumed as part of a balanced diet, we recommend a hearty intake of fruit and vegetables, washed down with a small amount of red wine.

Anti-oxidants work when applied topically, also. A common analogy is that of a slice of apple rubbed with lemon juice. Left unprotected, the apple will quickly turn brown as it oxidises, but the lemon juice (rich in vitamin C) slows the process. Applying anti-oxidants to the skin has a similar effect.
