—Freckling: "People who freckle are more likely to develop skin cancer than other people because freckling is a sign the skin cannot adequately pigment itself evenly. If you have children who freckle, please, please teach them to wear a sunscreen."
—Acne: "Many people believe acne is lessened by sun exposure. Sometimes this is so, but there are many people whose acne doesn't improve, it gets worse. No one knows exactly why this is so and it's difficult to predict what will happen to any one person."
—Spotting: "Those brown spots you see on the back of the hands or face that we used to call 'liver spots’ don’t have anything at all to do with your liver. It has to do with sun exposure.”
Fortunately, there are (wo< things the average person can do to limit damage from the sun.
First, don’t expose yourself to direct sunlight for extended periods of time. Once the damage is done, Dr. Barker says, there is no way to undo it.
Second, if you are going to bp in the sun, even for short periods of time, use a sunscreen with a high SPF (Sun Protection Factor). The higher the SPF number, the greater the amount of ultraviolet radiation it will absorb before your skin is damaged. Use of a high SPF sunscreen is particularly important for persons who sunburn easily.
