Polymorphous light eruption is a skin condition in which a person develops a sensitivity to the sun’s UV rays (UVA light is the usual culprit). This sensitivity will often result in an itchy rash, consisting of small red bumps and raised patches of skin, similar to hives in appearance. Polymorphic light eruptions tend to affect people more in the spring and summer months, when a person’s exposure to sunlight is increased. The skin may harden to the sun as the summer progresses so they may not develop the condition in late summer. Typically more females than males are affected by this condition. Sun avoidance and protective measures such as the use of a broad spectrum sunscreen are effective in preventing the occurrence of rashes. In most cases, polymorphic light eruption rashes will resolve on their own without treatment. However, persistent and recurring cases may require procedures such as phototherapy. Always rule out systemic lupus as this can also cause photosensitive rashes.
