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.
