Can coffee be used as sunscreen substitute?

Rubbing coffee on your skin could one day be a good alternative to sunscreen.

Research suggests caffeine guards against some skin cancers by inhibiting a protein enzyme in the skin.

In a new study from Rutgers University, researchers genetically modified a group of mice to reduce the enzyme, then exposed them and a control group to ultraviolet light.

The genetically-modified mice had 69 percent fewer tumors.

Now, scientists want to study if applications of caffeine reduce skin cancers.
