    A sunburn is inflammation (a reaction by your body's immune system) caused by too much UV (ultra-violet) radiation, which is part of the sunshine.

Further, the damage reduces the skin's ability to repair itself, speeding up the formation of wrinkles and other signs of aging.

    It typically resolves within 3-5 days for mild sunburns, and 7-14 days for blistering episodes

    Common
