Staying aware of the danger of childhood sun exposure and educating children to the risks of the sun are key to the future prevention of skin cancer. Using a sunscreen–SPF 15 or greater–during a child's first 18 years can lower the risk of certain skin cancers by 70 to 80 percent. Protective clothing and sun avoidance should also be practiced. The American Academy of Dermatology's "Block the Sun, Not the Fun" program will bring these important messages to school–age children nationwide.

Wrinkling and discoloration (photoaging) of the skin are directly related to sun exposure. UV radiation not only destroys collagen–a fiberlike molecule that gives strength and contour to the skin–but also prevents new production of this important molecule. Photoaging can occur all year long, since UVA wavelengths remain constant throughout the year and also pass through window glass.

Treatment of photoaging focuses on stimulating new collagen production. Both prescription and nonprescription vitamin A acids and retinol, vitamin C, and alpha– and beta–hydroxy acids, are currently popular for home use.
