By Mayo Clinic staffPolymorphous light eruption treatment usually isn't necessary because the rash typically resolves on its own within a few days but may last a week or more. To lessen the reaction and prevent future episodes:
- Limit time spent in the sunlight.
- Use sunscreen and wear protective clothing.
- Consider using a nonprescription anti-inflammatory cream, which may help soothe your skin and reduce itching and discomfort.
If prevention steps aren't effective and you continue to experience sun reactions, your doctor may prescribe a medication, such as a corticosteroid cream, to reduce the inflammation.
