UV radiation can penetrate living tissue and damage the DNA in the nucleus of its cells. Our skin has the ability to produce a pigment called melanin that makes it darker (like getting a ten) and then the darker pigment helps stop UV rays from damaging deeper tissues. Too much exposure to UV light can even damage the melanocytes (the cells that produce the melanin pigment) and you can develop skin cancer. The deadliest skin cancer is malignant melanoma and if you suspect that you may have it you should get medical attention right away.
