Whether you're heading to the beach or the sunny heights, protect your skin from sun damage and the risk of skin cancer. The American Cancer Association recommends a minimum of SPF 30 to protect against UVA and UVB radiation. UVA contributes to dark patches, lose skin, premature aging, and DNA damage. UVB causes eye problems, sunburn, and also DNA damage; it is the DNA damage that causes skin cancer, the most dangerous of which is melanoma. A total of 3.5 million cases of non-melanoma skin cancer are diagnosed every year in the United States. Learn more at cancer.org.
