It is noticed that most of the sun alergy cases are not really sun alergies in which the immune system reacts to the typical allergen like pollen. These conditions could be due to the hypersensitivity to the sun which is known as Polymorphous Light Eruption – PMLE.

The body starts developing rashes during every spring when the sunlight gets more extreme.

Such rashes are noticed only on the skin part that is exposed to the sun. Even the red blemishes are formed that may be elevated, uneven or hive like. Though, Polymorphous Light Eruption affects both men and women or adults and children in the same manner, but the problem specifically starts between the age of 20 and 35 years. Even some evidences of hereditary predisposition are found in the Americans.
