Topical methyl aminolevulinate photodynamic therapy for the treatment of folliculitis

Photodynamic therapy (PDT) has been found to be effective for the treatment of acne vulgaris. We now wish to present a case series of seven patients who were successfully treated for chronic folliculitis with PDT after photosensitization with topical methyl aminolevulinate. The folliculitis had occurred in areas of acne‐prone skin of the patients, mainly after long‐term administration of antibiotics.
