Baste with oil

APPLYING virgin olive oil to your skin after sunbathing protects you against
skin cancer, claim Japanese scientists. They have found that using it as an
after-sun lotion slows tumour growth in mice.

Ultraviolet (UV) radiation in sunlight creates free radicals which damage
DNA in skin cells and trigger abnormal growth, often leading to skin cancer.
Antioxidants such as vitamin E mop up these radicals and are thought to
protect against UV damage. So Masamitsu Ichihashi and his colleagues from
the Kobe University School of Medicine decided to find out if olive oil,
which is a potent source of antioxidants, provides UV protection.

They gave hairless mice three UV sessions a week under a sunlamp. Five
minutes after the treatment, they painted their skin with either regular or
extra virgin olive oil. After 18 weeks, control mice started to grow skin
tumours, and mice treated with regular olive oil fared little better. But
mice daubed with virgin olive oil took an extra six weeks to show any sign
of cancer. What's more, their tumours were smaller, less frequent and there
was less DNA damage to skin cells.

The researchers are quick to point out that olive oil isn't a sunscreen. But
they claim that rubbing on olive oil after sunbathing could help protect
skin from UV damage.
