What you should know about the sun… It causes 90% of all skin cancers:
Who needs to use sunscreen?
Everyone! More than 4.5 million skin cancers are diagnosed in more than 2 million people annually. Many studies have found an association between sunburns and enhanced risk for melanoma, the deadliest form of skin cancer. The American Academy of Dermatology recommends that, regardless of skin type, a broad-spectrum (protects against UVA and UVB rays), water-resistant sunscreen with a Sun Protection Factor (SPF) of at least 30 should be used year-round.
What are UVA and UVB rays?
Sunlight consists of two types of harmful rays: ultraviolet (UVA) rays and ultraviolet B (UVB) rays. UVA rays (which pass through window glass) penetrate deeper into the dermis, the thickest layer of the skin. UVA rays can cause suppression of the immune system, which interferes with the immune system’s ability to protect you against the development and spread of skin cancer. UVA exposure also is known to lead to signs of premature aging of the skin such as wrinkling and age spots.
The UVB rays are the sun’s burning rays (which are blocked by window glass) and are the primary cause of sunburn. A good way to remember it is that UVA rays are the aging rays and UVB rays are the burning rays. Excessive exposure to both forms of UV rays can lead to the development of skin cancer.
