A photosensitivity condition where papules, vesicles, and erythema appear after spring or early summer sun exposure
Recurs seasonally and is a delayed-type hypersensitivity reaction to UV. Gradual sun exposure may build tolerance.
Main causes & characteristics of Polymorphous Light Eruption
Polymorphous light eruption (PMLE) is known as a delayed-type hypersensitivity reaction to sudden UV exposure in spring and early summer. Skin that has had minimal sun exposure during winter may develop papules, vesicles, and erythema upon encountering intense UV radiation, and a tendency to recur each year at the same season is noted. Gradual incremental exposure is known to induce tolerance in some individuals.
Managing Polymorphous Light Eruption
Starting in early spring, gradually increasing sun exposure and consistently applying sunscreen is recommended. Cooling and soothing exposed areas and following up with moisturization may help, and it is advisable to avoid intense midday sunlight. If symptoms recur severely each year, consulting a dermatologist is recommended to explore management options such as photohardening.
