PATHOLOGY

Detailed explanation-1: -Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the sun.

Detailed explanation-2: -Sunburn is an inflammatory reaction to ultraviolet (UV) radiation damage to the skin’s outermost layers. At the heart of it all is melanin, a pigment that gives your skin its color and defends it against the sun’s rays.

Detailed explanation-3: -Blood vessels dilate to increase blood flow and bring immune cells to the skin to help clean up the mess. All this causes the redness, swelling and inflammation we associate with a sunburn.”

Detailed explanation-4: -Sunburned skin rarely becomes infected, but if an infection develops, healing may be delayed. A doctor can determine the severity of an infection and prescribe antibiotics if necessary. Sunburned skin begins healing by itself within several days, but complete healing may take weeks.
