Sunlight is composed of two harmful types of radiation: ultraviolet A (UVA) and ultraviolet B (UVB) rays. Both types have been known to lead to skin cancer. Research has shown that UVA rays age the skin and may lead to age spots and wrinkles. They also suppress the immune system, which protects against infection and cancer. UVB rays cause the most immediate damage to the skin. They penetrate the first layer of skin (epidermis) and act on the cells that produce melanin, which can result in a darker skin, a painful sunburn, and even skin cancer.
Use a sunscreen and wear protective clothing to safeguard your skin from the sun’s harmful rays.
