Expression of polymorphous light eruption (PMLE) may range from an insignificant, mild rash to severe disease affecting the patient's quality of life. Some PMLE patients experience a less severe reaction with each consecutive year, but many patients have reactions that may worsen with time without appropriate treatment. Each case should be evaluated individually.

PMLE is a chronic condition; the average time to resolution is long and can reach up to 30 years.

Richards et al found that emotional distress attributable to PMLE occurred in greater than 40% of individuals. [1] Women more than men associated more severe consequences with their PMLE and experienced more emotional distress.
