UVB (beta) is short-wave UV (ultraviolet) radiation which ranges from 280 nm to 315 nm in wavelength. UVB radiation is much stronger than UVA radiation, and affects mainly outer skin layers. It is the most common cause of sunburn, but it also contributes to premature ageing of the skin, wrinkles and skin cancer.
