Pityriasis versicolor: Regaining the lost pigmentation

Among the metabolites the Malassezia synthesizes is pityriacitrin that absorbs ultraviolet (UV) light. The hypopigmentation is accentuated if the surrounding unaffected skin becomes tanned. 

Patients should be informed that the hypopigmentation will take time to resolve and is not a sign of treatment failure.  Repigmentation may take several months even when the organisms have been destroyed. After the fungal disease is cured, an effort can be made to regain the lost pigmentation through UV light exposurePrevention of recurrence is also important. 

The patient chose to shorten the time needed for repigmentation by receiving UV light sessions.
