REALITY: You might not be aware of secondary sun exposure. It accumulates over the years as a result of brief daily activities, such as taking the dog out and going to work. Over time, this build-up can seriously damage your skin. Skin cancer is the most common type of cancer. It is also the easiest cancer to avoid.
