Scientists made a drug that copies sunlight. It tricks our skin into making melanin. Melanin gives our skin its colour. The scientists say the drug is good for our health. It could stop skin cancer. It could also keep us younger looking. Lots of sun can give us skin cancer. It also makes our skin look old and it gives us wrinkles.
The drug could give us a suntan. We get a suntan from the Sun, but the Sun has harmful UV rays. These damage our skin. They make some skin turn red. Melanin is our natural sunblock. It protects the skin from the Sun. The drug could help fight skin cancer. This is the most common type of cancer.
