Polymorphous light eruption, colloquially known as 'sun poisoning' or 'sun allergy,' is a condition in which individuals who are sensitive to sunlight develop a rash following sun exposure. Doctors sometimes refer to this condition as polymorphic light eruption, and the rash it produces is typically red and bumpy. The bumps may be slightly elevated off of the skin's surface, and they may be itchy. The rash associated with this condition normally appears within thirty minutes of sun exposure, and patients experience more eruptions (rashes) in the spring and summer. To diagnose polymorphous light eruption, a physical examination may be all that is needed.
