Australian scientists have come out with a new sunscreen by studying the Great Barrier Reef, which is the world's largest coral reef system.
It was amazing to study the way the reef's corals protect themselves from ultraviolet light for millions of years. Scientists found the presence of natural filters which keep away the damaging rays.
Researchers came out with a safe and powerful sunscreen which can protect against harmful UV radiation which causes sunburn and skin cancer.
"The filters are clear in colour, virtually odourless and very stable, which makes them easy to be incorporated into any emulsion," said scientist Dr Mark York.
Scientists hope that the sunscreen will be available globally within five years.
