Skin cancer affects 2 million individuals annually in the United States.1 Ultraviolet light is the primary cause of skin cancer and sunscreens provide UV protection when sun avoidance is not possible. Because skin cancers can result in substantial morbidity and mortality, it is generally recommended that patients be advised to use sunscreen whenever possible while exposed to sunlight.
