Long term exposure to the sun or repeated sun burns can break down the elastic tissues in your skin and may cause solar keratosis (care-a-toe-sis). solar keratoses are flat, pink, scaly spots that grow on sun-damaged skin. They are more frequent and more numerous in fair-skinned individuals, and they are a type of growth that can turn into skin cancer. Monthly self-exams of your skin and routine use of sun-protection products are good ways to lower your risk of solar keratoses. Early detection is your greatest asset, so don't hesitate to contact your dermatologist immediately if you notice any changes in your skin. Stay alert. If a birth mark, mole, or other spot on your skin starts to change, see your healthcare provider.
