3. Photosensitivity and PMLE

While every patient with polymorphic light eruption has a sensitivity to sunlight, this sensitivity lessons with repeated exposure to sunlight. The resulting rash is most likely to occur in the first one or two exposures to sunlight, with repeated exposures to sunlight weaker rashes. Episodes of rash are less likely to recur later on in the season. People with this condition can outgrow the condition after several years and repeated exposure to sun, lessening their photosensitivity with repeated exposure to the sun. There are also links to vitamin D deficiency.
