Risk factorsBy Mayo Clinic staff
Although anyone can develop polymorphous light eruption, several factors are associated with an increased risk of the condition:
- Women are more likely to develop the disorder.
- The first episode most often appears during the teenage years or 20s.
- People with fair skin or those living in northern regions are more likely to develop the disorder.
- A family history of polymorphous light eruption among some people with the condition suggests a possible genetic risk factor.
