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.
THE UV SPECTRUM. UV-A, UV-B, and UV-C are all part of the ultraviolet light spectrum. UV-A results in skin tanning and is used in medicine to treat certain skin disorders. UV-B has a very high penetrating ability and results in sunburn.
