Is reddening of the skin occurring after exposure to the sun or other ultraviolet light. It happens when the amount of sun exposure exceeds the ability of the body to protect the skin. The body protects the skin through melanin pigment which acts like an umbrella that covers the skin. Sunburn is a burn which is most commonly a first degree burn part I, II, more severe or deep sunburns can lead to second degree burns with the formation of blisters and rarely third degree burns part I, II. Very light skinned people can have sunburns in less than 15 minutes of exposure to midday sun while dark skinned people may tolerate the same exposure for hours.
Symptoms of sunburn typically don’t develop until about 2-6 hours after sun exposure, while in children it happens as little as 15-30 minutes after being exposed to the sun without adequate protection.
