Conventional Photodynamic Therapy Versus Daylight Photodynamic Therapy for The Treatment of Acne Vulgaris

Summary

Photodynamic therapy (PDT) is considered an effective treatment for acne vulgaris. The study aims to determine whether treatment with daylight as an illumination source is as effective as conventional, red light illumination. 15 patients with acne vulgaris received 4 treatment sessions at three-week intervals. First, 5-aminolevulinic acid (ALA) was applied to the entire face. Then the face was divided into two symmetrical contralateral treatment areas: the left was covered with a light-impermeable dressing, while the right face was exposed to sunlight. After 2 hours outdoors, the right side of the face was covered, and the left half was illuminated with red light.
