A. The sun produces invisible rays called ultraviolet-A (UVA) or ultraviolet-B (UVB) that can damage the skin. Too much sun can cause sunburn, skin texture changes, and skin cancers. Rashes also can be attributed to sunlight. Even on cloudy days, UV radiation reaches the earth and can cause skin damage.
There are 3 types of ultraviolet (UV) rays: 1  Ultraviolet A rays (UVA) make up most of the sun's natural light. They can penetrate deep into the skin, causing wrinkles and premature aging of the skin.  Ultraviolet B rays (UVB) are the main cause of sunburn. They are nearly 1,000 times stronger than UVA rays.
