Your skin has a memory of every incidence of sun damage. Avoid Intense Overexposure to Sunlight Staying out of the sun is obviously the best way to prevent skin damage. It s important to avoid episodes of excessive exposure, particularly during the hours of 10 A.M. to 4 P.M. when sunlight pours down 80 percent of its daily UV dose. Reflective surfaces, such as water, sand, and concrete should also be avoided. Remember, clouds and haze are not protective, and in some cases may intensify UVB rays.
Higher altitudes appear to reduce the time it takes to burn.
One study for example, revealed that an average complexion burns in just six minutes at 11,000 feet at noon, compared to 25 minutes at sea level in a temperate climate. Antioxidants Antioxidants are substances that act as scavengers of oxygen-free radicals unstable particles that can damage the body's cells and even their genetic material. The most well known antioxidants are vitamins A, C, E, and beta-carotene. A and E were associated with a lower risk for basal cell carcinoma. Sunscreens Sunscreen, used generously, may help prevent aging as well as skin cancer.
