Of course at this stage, the experiments have only been conducted on mice, but it paves the way for further tests in humans. Here is what SMH had to say about the discovery:

A tiny red berry celebrated for its antioxidant qualities may also help protect against skin damage that leads to cancer, researchers believe.

Scientists at the University of Sydney fed diluted juice from the goji berry to mice in the laboratory and found it protected them against the same sun damage as other mice when exposed to harsh UV rays.

Another experiment showed skin cancer advanced slower in mice that had drunk goji juice

"The goji berry-drinking mice had significantly less inflammation of the skin," said Dr Reeve, who is a scientific adviser to a company that distributes the juice.

"And the juice seemed to protect the immune system because they didn’t get immuno-suppression which is a major risk factor for skin cancer development in chronically over-exposed skin."

It also appeared to have protective properties against skin cancer growth, she said, with another experiment showing skin cancer-induced mice had significantly slower growing tumours.

This doesn’t mean you can stop wearing sunscreen but adding goji juice to your diet could be beneficial to your skin.
