During the past decades doctors have become increasingly aware of the increase in skin cancer in the United States and that all people need to protect themselves from ultraviolet radiation (UV). The harm caused by UV includes premature aging (such as wrinkling and age spots), skin cancer, and permanent, sometimes blinding, damage to eyes. Other medical conditions, such as lupus, can be made much worse by UV exposure. In addition, many people take drugs, such as antibiotics, antidepressants, diuretics and retinoids, that make them extremely sun sensitive. Doctors everywhere agree that education is critical to stopping the epidemic of sun related diseases - especially skin cancer.
