Polymorphous Light Eruption is a rash on the skin caused by exposure to sunlight. While its cause is largely unknown, it is a condition that does not require treatment as much as it is a condition that is largely preventable.
The condition usually occurs within a day or two after exposure to the sun and lasts for a week or so. While some scholars say that Polymorphous Light Eruption is sometimes passed genetically, no hard proof of that has been shown in clinical research.
It is estimated that around 15% of Americans, heavily concentrated in the northern states, suffer from Polymorphous Light Eruption. While it is not considered a deadly or an aggressive condition, it has been proven that prolonged exposure to the UVA and UVB rays of the sun can cause skin cancer and other conditions that are an immediate danger to ones health.
