Human body produces the protective pigment in the skin to fight against the ultraviolet rays from sun. This pigment is known as Melanin. When body is unable to produce sufficient amount of melanin and is exposed to sun during 10 am to 3pm, the skin reacts to sun radiations and causes sunburn.What are the Symptoms of Sunburn?
Usually, after 2-3 hours of sun exposure the skin turns red and feels constant itching. Then when scratched with nails it further deteriorates and leads to skin irritation. This all happens within 12 hours of exposure of tender skin to damaging ultraviolet radiations emitted from sun. This is also referred as first-degree sunburn. However this could vary from one person to another depending on the sensitivity of skin.
