People who have very fair skin should cover up as much as possible to avoid a sunburn which can lead to skin cancer development.

While these are quite well-known means of preventing skin cancer, researchers have now developed a new way to help beat skin cancer that lets people know their level of UV radiation exposure. Researchers at RMIT University in Melbourne Australia along with a research team at the University of Granada have developed a bracelet that people can use when they go out in the sun.

This bracelet is made up of four emoticon faces. The faces are...
